How does target duration affect object substitution masking?

Object substitution masking (OSM) is typically studied using a brief search display. The target item may be indicated by a cue/mask surrounding but not overlapping it. Report of the target is reduced when mask offset trails target offset rather than being simultaneous with it. We report 5 experiments investigating whether OSM can be obtained if the search display is on view for a period of up to 830 ms but cueing of the target location is delayed. The question of interest is whether OSM must reflect the initial response of the visual system to target onset or whether it can arise in other ways, possibly during the transition from a pre-attentive representation of the target item to an attentional representation of it. Our results show that OSM decreases in strength as target duration increases. An explanation is suggested in terms of the object individuation hypothesis (Lleras & Moore, 2003).

How does processing affect storage in working memory tasks? Evidence for both domain-general and domain-specific effects.

[Correction Notice: An erratum for this article was reported in Vol 37(3) of Journal of Experimental Psychology: Learning, Memory, and Cognition (see record 2011-08992-004). Chen and Cowan (2009) is correctly cited in the body of the article but the reference at the end of the article is incorrect. The correct reference is in the correction.] Two studies that examine whether the forgetting caused by the processing demands of working memory tasks is domain-general or domain-specific are presented. In each, separate groups of adult participants were asked to carry out either verbal or nonverbal operations on exactly the same processing materials while maintaining verbal storage items. The imposition of verbal processing tended to produce greater forgetting even though verbal processing operations took no longer to complete than did nonverbal processing operations. However, nonverbal processing did cause forgetting relative to baseline control conditions, and evidence from the timing of individuals' processing responses suggests that individuals in both processing groups slowed their responses in order to “refresh” the memoranda. Taken together the data suggest that processing has a domain-general effect on working memory performance by impeding refreshment of memoranda but can also cause effects that appear domain-specific and that result from either blocking of rehearsal or interference.

When does mimicry affect evaluative judgment?

We investigated the effect of subliminally presented happy or angry faces on evaluative judgments when the facial muscles of participants were free to mimic or blocked. We hypothesized and showed that subliminally presented happy expressions lead to more positive judgments of cartoons compared to angry expressions only when facial muscles were not blocked. These results reveal the influence of socially driven embodied processes on affective judgments and have also potential implications for phenomena such as emotional contagion.

How does one decide about ESP?

Comments on the article by J. C. Crumbaugh entitled "ESP and flying saucers: A challenge to parapsychologists" (see record 2005-12015-013). The present author takes issue with two major points made by Crumbaugh. The first has to do with his proposal as a scientific procedure, the second with his conception of where parapsychology stands today. But first there are two minor factual errors that should be corrected. In one lesser slip Crumbaugh refers to "most reputable experimentalists" being led to "lose interest in ESP." As a matter of fact, there has never been any such wholesale interest to be lost, either on the part of experimentalists in psychology or out of it, arid whether reputable or not. The other rather small correction deals with Crumbaugh's remark that "Rhine has rejected the observations of an experiment by a skeptical committee or individual..." The present author states that at no time has he rejected any such observation; moreover there are, as Crumbaugh himself doubtless knows, significant experimental results of ESP experiments conducted with observers present, some of them known to be skeptical.

How does context affect assessments of facial emotion? The role of culture and age.

People from Asian cultures are more influenced by context in their visual processing than people from Western cultures. In this study, we examined how these cultural differences in context processing affect how people interpret facial emotions. We found that younger Koreans were more influenced than younger Americans by emotional background pictures when rating the emotion of a central face, especially those younger Koreans with low self-rated stress. In contrast, among older adults, neither Koreans nor Americans showed significant influences of context in their face emotion ratings. These findings suggest that cultural differences in reliance on context to interpret others' emotions depend on perceptual integration processes that decline with age, leading to fewer cultural differences in perception among older adults than among younger adults. Furthermore, when asked to recall the background pictures, younger participants recalled more negative pictures than positive pictures, whereas older participants recalled similar numbers of positive and negative pictures. These age differences in the valence of memory were consistent across culture. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Why does a red snake in the grass capture your attention?

It has been suggested that affective stimuli automatically capture attention; this preferential processing is thought to be related to the evolutionary significance of affective stimuli. However, recent evidence suggests that perceptual salience alone might explain why some affective stimuli are more likely to influence attentional processes in certain contexts. In this study, we manipulated affective and perceptual salience to better understand how affective information is processed and how it impacts attentional processes in different contexts. We used stimuli that are both affectively and perceptually salient, while varying the task requirement to encourage the processing of perceptually salient (Experiment 1) or affectively salient (Experiment 2) information. This design made it possible to observe independent and interdependent relationships between perceptual and affective salience. The results showed that when the task encouraged the processing of perceptually salient information, affective salience did not influence task performance. In contrast, when the task encouraged the processing of affectively salient information, affectively salient information impaired task performance. The findings suggest that the affective nature of the stimuli does not always influence attentional processes. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Does emotion processing require attention? The effects of fear conditioning and perceptual load.

This study examined the impact of perceptual load on the processing of unattended threat-relevant faces. Participants performed a central letter-classification task while ignoring irrelevant face distractors, which appeared above or below the central task. The face distractors were graded for affective salience by means of aversive fear conditioning, with a conditioned angry face (CS+), an unconditioned angry face (CS?), and a neutral control face. The letter-classification task was presented under conditions of both low and high perceptual load. Results showed that fear conditioned (i.e., CS+) angry face distractors interfered with task performance more than CS? angry or neutral face distractors but that this interference was completely eliminated by high perceptual load. These findings demonstrate that aversively conditioned face distractors capture attention only under conditions of low perceptual load.

How do changes in speed affect the perception of duration?

Six experiments investigated how changes in stimulus speed influence subjective duration. Participants saw rotating or translating shapes in three conditions: constant speed, accelerating motion, and decelerating motion. The distance moved and average speed were the same in all three conditions. In temporal judgment tasks, the constant-speed objects seemed to last longer than the decelerating objects, which in turn seemed to last longer than the accelerating stimuli. In temporal reproduction tasks, the difference between accelerating and decelerating stimuli disappeared; furthermore, watching an accelerating shape lengthened the apparent duration of the subsequent (static) display. These results (a) suggest that temporal judgment and reproduction can dissociate for moving stimuli because the stimulus influences the apparent duration of the subsequent interval, and (b) constrain theories of time perception, including those which emphasize memory storage, those which emphasize the existence of a pacemaker-accumulator timing system, and those which emphasize the division of attention between temporal and non-temporal information processing.

How does religiosity enhance well-being? The role of perceived control.

Religiousness and spirituality (R/S) are consistently linked with positive indicators of well-being, but the mechanisms behind these associations remain largely unknown. We hypothesize that an individual's level of perceived control (PC) acts as a mediator of this relationship and that this effect is stronger in older adults. Participants were 529 adults from the Notre Dame Study of Health and Well-Being (aged 31–88). Regression analyses tested both mediating and moderating functions of PC for three different R/S components (religious practices, daily spiritual experiences, and religious/spiritual coping); composite variables were used for PC and subjective well-being (SWB) in all analyses. These effects were tested using the full sample, as well as separately by age group (early midlife, aged 31–49; late midlife, aged 50–59; and later life, aged 60 and over), in order to discover any age differences that may exist. Results revealed differences by both R/S dimension and age group: PC partially mediated the religious practices-SWB relationship in the full sample and in the later life group; the effects of religious/spiritual coping and spiritual experiences on SWB were partially mediated by PC in the full sample, the late midlife group, and the later life group; and none of the R/S-SWB relationships were mediated in the early midlife group. Moderating effects were indicated by significant interactions between PC and spiritual experiences in the full sample, PC and religious coping in the full sample, and PC and religious practices in the later life group.

How do constraints on leaving a marriage affect behavior within the marriage?

Like relationship satisfaction, constraints on leaving a relationship have been described as a component of global commitment. But do constraints increase or decrease efforts to maintain the relationship? To address this question, the authors of the current article describe 3 independent studies of spouses and married couples. Across all studies, wives who perceived more constraints on leaving the marriage exhibited lower levels of negative behavior only when their husbands were relatively unconstrained. In Study 3, this association was especially pronounced among less satisfied wives. In Study 2, spouses' perceived constraint also interacted to predict husbands' behavior, but in the opposite direction: Husbands who perceived more constraints behaved less negatively when their wives were similarly constrained but more negatively when their wives were less constrained. These results highlight differences in behavior between couples who persist in marriage because they desire to and those who endure because they have to, raising questions about measures of global commitment that obscure these distinctions. They also highlight the need for a dyadic perspective on the forces that keep relationships together. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Do intercultural experiences affect attitudes?

The attitudes and personality traits of 183 secondary school and college students who went to Europe in the summer of 1950 were tested before and after their trip. The principal findings of the study are: (1) S's who establish close personal ties with Europeans are more likely than others to engage in international oriented activities. (2) An unstructured, heterogeneous intercultural experience does not have a significant impact on social attitudes. (3) Knowledge of a S's pre-existing attitudes is a better predictor of response to an intercultural experience than knowledge of the experience itself. (4) There are significant personality differences between world minded and nationalistic S's. (5) Changes in attitude can be measured over a two month interval.

The effect of valence on young and older adults’ attention in a rapid serial visual presentation task.

Using a rapid serial visual presentation task, the authors examined how the emotional valence of a word affected young and older adults’ abilities to detect another word that closely followed it in temporal proximity. Both age groups detected neutral words better when such words followed a positive or negative arousing word rather than a neutral arousing word. These results suggest that emotion influences attention in a similar fashion for young and older adults. Despite evidence that older adults can sometimes show a “positivity effect” in memory, we found no evidence of increased attention toward positive words for older adults.

Are processing speed tasks biomarkers of cognitive aging?

We examined the association between 5 processing speed measures and general cognitive ability in a large (>900) sample of relatively healthy men and women at age 70. The processing speed tests were the Wechsler Digit Symbol-Coding and Symbol Search, simple reaction time, 4-choice reaction time, and inspection time. To inquire whether the processing speed tasks might be biomarkers of cognitive aging, we examined the attenuations in their associations with general cognitive ability after adjusting for cognitive ability measured almost 60 years earlier. With the exception of inspection time, the attenuations were substantial. Inspection time was the only processing speed measure—all of which were measured at age 70—whose correlation with cognitive ability at age 70 was significantly greater than the correlation with cognitive ability at age 11. In old age, individual differences in most commonly used measures of processing speed are largely dependent on childhood cognitive ability. For all processing speed tasks, a little variance is left that appears to be related to aging differences. Inspection time, the marker that was least dependent on childhood intelligence, should be considered further as one biomarker of cognitive aging.

How does cognitive control reduce anger and aggression? The role of conflict monitoring and forgiveness processes.

It is well-established that superior cognitive control abilities are associated with lower levels of anger and aggression. However, the precise emotion regulation operations underlying this relationship have been underspecified and underexplored in previous research. Drawing on neuropsychological models of cognitive control, the authors propose that limited capacity resources can be recruited within a hostile situation to promote a process of forgiveness. The results of 2 studies supported this proposal. Across studies, individual differences in hostility-primed cognitive control were assessed implicitly. In Study 1, hostility-primed cognitive control predicted less aggressive behavior in response to a laboratory provocation. Moreover, forgiveness mediated these effects. In Study 2, hostility-primed cognitive control predicted forgiveness of provocations in participants' daily lives and subsequent reductions in anger. In sum, the results contribute to a systematic understanding of how cognitive control leads to lower levels of anger and aggression. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Perception of and psychological coping with medical technology. How does the patient perceive percutaneous transluminal coronary angioplasty?

BASIC REMARKS: Since, as a result of technological progress, ever more interventions are being carried out in the conscious patient without anesthesia or sedation, psychological coping is an important aspect. METHODS: Over a period of one year, all patients undergoing coronary artery dilatation at the University Hospital, Frankfurt, were admitted to the study in which the patients and their spouses, as well as the physicians involved were questioned (individual questioning, questionnaires, interviews). In addition, a catamnestic follow-up examination was performed. RESULTS: In addition to numerous other results, the following major points can be made: most patients coped with the stressful situation by adopting an optimistic attitude, which was combined with trust in the physician and the procedure employed. A very small group of patients can be considered to suffer from appreciable depressivity/anxiety and requires psychotherapeutic support. Days and weeks after the procedure there is a delayed phase of "late coping". In the patients with no major persisting symptoms, there is an increasing tendency in this period to play down the situation, with the result that there may be a lack of readiness to admit the need to change possibly dangerous habits and adopt a different life style.
