Understanding of and reasoning about object–object relationships in long-tailed macaques?

Diagnostic reasoning, defined as the ability to infer unobserved causes based on the observation of their effects, is a central cognitive competency of humans. Yet, little is known about diagnostic reasoning in non-human primates, and what we know is largely restricted to the Great Apes. To track the evolutionary history of these skills within primates, we investigated long-tailed macaques’ understanding of the significance of inclinations of covers of hidden food as diagnostic indicators for the presence of an object located underneath. Subjects were confronted with choices between different objects that might cover food items. Based on their physical characteristics, the shape and orientation of the covers did or did not reveal the location of a hidden reward. For instance, hiding the reward under a solid board led to its inclination, whereas a hollow cup remained unaltered. Thus, the type of cover and the occurrence or absence of a change in their appearance could potentially be used to reason diagnostically about the location of the reward. In several experiments, the macaques were confronted with a varying number of covers and their performance was dependent on the level of complexity and on the type of change of the covers’ orientation. The macaques could use a board’s inclination to detect the reward, but failed to do so if the lack of inclination was indicative of an alternative hiding place. We suggest that the monkeys’ performance is based on a rudimentary understanding of causality, but find no good evidence for sophisticated diagnostic reasoning in this particular domain.     

How similar are recognition memory and inductive reasoning?

Conventionally, memory and reasoning are seen as different types of cognitive activities driven by different processes. In two experiments, we challenged this view by examining the relationship between recognition memory and inductive reasoning involving multiple forms of similarity. A common study set (members of a conjunctive category) was followed by a test set containing old and new category members, as well as items that matched the study set on only one dimension. The study and test sets were presented under recognition or induction instructions. In Experiments 1 and 2, the inductive property being generalized was varied in order to direct attention to different dimensions of similarity. When there was no time pressure on decisions, patterns of positive responding were strongly affected by property type, indicating that different types of similarity were driving recognition and induction. By comparison, speeded judgments showed weaker property effects and could be explained by generalization based on overall similarity. An exemplar model, GEN-EX (GENeralization from EXamples), could account for both the induction and recognition data. These findings show that induction and recognition share core component processes, even when the tasks involve flexible forms of similarity.     

Can mindfulness modify your thoughts? A study in the context of social phobia

IntroductionSocial phobia is said to be the commonest anxiety disorder (Furmark, 2002). Cognitive Behavior Therapy appears to be the most recommended form of psychological treatment for this condition (Federoff & Taylor, 2001; Willutzki et al., 2012). Dismantling studies have raised doubts regarding the utility of cognitive restructuring in bringing about decrease in symptoms (Barrera et al., 2016; Pompoli et al., 2018). Mindfulness, a ‘third-wave’ concept, seems to contradict the philosophy of ‘restructuring’ with its apparent stress on non-judgmental observation (Hayes, 2004). This approach postulates that acceptance of cognitions and emotions as therapeutic in contrast to traditional cognitive behavior therapy approach, which advocates restructuring and modifications of cognitions.ObjectiveThe current study attempted to study the ‘restructuring’ effects of mindfulness in persons with social phobia.MethodThirty-nine clients with a primary diagnosis of social phobia (ICD – 10) participated in the Mindfulness Integrated Cognitive Behavior Therapy (MICBT) program, which consisted of eight sessions. MINI International Neuropsychiatry Interview Plus, Liebowitz Social Anxiety Scale, Fear of Negative Evaluation, Meta Cognitions Questionnaire and Five-Facet Mindfulness Questionnaire were administered pre and post of the therapeutic program.ResultsThe results demonstrated that MICBT had a significant effect on reducing the scores on fear of negative evaluation and bringing about changes in metacognitions.ConclusionMindfulness could be sufficient as a therapeutic strategy to bring about changes in the cognitions of clients with social phobia without using cognitive restructuring.     

Where did I park? A naturalistic study of spatial memory

A naturalistic study of spatial memory having temporary utility was conducted using 32 faculty and staff of a university, who park in non-reserved parking spaces, as subjects. The subjects, who were unaware of the study until interviewed, were asked to indicate on a map the exact location where they had parked their car on that day and on each of the three preceding days. Whereas retention accuracy decreased significantly across days, the recency effect was weak and overall retention proved to be very accurate. Of the subjects who varied their parking location, 88 per cent were able to indicate within three spaces where they parked on the day of the interview, and 58 per cent on the most remote day. Younger females made significantly larger retention errors across the four days than older females and younger and older males. Subjects' overall retention accuracy correlated with their overall confidence in their recollections (γ = .72). Daily ratings of ‘how busy on the job’, reported times left campus each day, parking location variability, particular parking lot used, and number of parking spaces in the distinct locations used were not significantly correlated with retention errors. In follow-up interviews, subjects reported preferring a behavioural, ‘park in a favourite spot’ strategy, with several types of imagery-based cognitive strategies being cited less frequently, and verbal encoding being the least often cited strategy.     

Does social dominance generate prejudice? Integrating individual and contextual determinants of intergroup cognitions

Social dominance orientation (SDO) has been proposed as an important variable in the explanation of prejudice. We distinguish between three conceptualizations of SDO: SDO as a personality trait (personality model), SDO as a moderator of the effects of situational variables (Person x Situation model), and SDO as a mediator of the effect of social position on prejudice (group socialization model [GSM]). Four studies (N = 1.657) looking at the relations between social positions, SDO, and prejudice in a natural setting and in a laboratory setting provide strong support for the GSM. In contrast to previous correlational findings, there is evidence of a cause (dominant social position), an effect (prejudice increases), and a mediator (SDO). These results suggest new perspectives on the integration of individual and contextual determinants of prejudice.     

Collectivize social support? Elements for reconsidering the social dimension in the study of social support

Psychological models of mental disorders play an important role in the explanation of psychological deterioration. Researchers from this area usually study several cognitive and behavioral variables to account for the onset and maintenance of depression. However, many authors have detected the need to include a "social dimension" in the explanation of deterioration. In this sense, social support has become a crucial aspect in the study of mental health, and the psychological literature on this topic has generated an intense debate about several facets of the positive impact of social networks on psychological well-being. In this article, the author defends that this increasing centrality of the concept has been accompanied by a psychological reductionism that is making the role of "social aspects" to explain psychological well-being more problematic. Implications of this reductionism are discussed, and an alternative proposal is made to overcome some theoretical and empirical problems related to social support research.     

Flashbulb memories in social groups: A comparative test–retest study of the memory of French President Mitterrand's death in a French and a Belgian group

Flashbulb memories are vivid and long-lasting memories for the reception context of an important public event (Brown & Kulik, 1977). They are assumed to be triggered by emotional factors (i.e., intensity of emotional feeling, appraisal of the original event) and by social factors (i.e., social sharing of the news, following media debate about the event). The present study investigated the memory for the death of the former President of France F. Mitterrand in two social groups, i.e., French and Belgian people. This study tests whether the flashbulb memory attributes, the memory for the original event, and the impact of the emotional and social determinants of flashbulb memory differed across groups. The results indicated that the flashbulb memory for Mitterrand's death is affected by group provenance, as French people showed higher levels of recall for the flashbulb memory attributes and their determinants than Belgian people. Time impaired recollections in both groups, so that flashbulb memories appear prone to decay and share the same destiny as ordinary memories. The theoretical construct of concern - as the most basic antecedent of emotional experiences and its related appraisal (Frijda, 1994) - is discussed in order to explain the differences in memory of the two social groups.     

Narcissism and the non-equivalence of self-esteem measures: A matter of dominance?

Previous research reveals a substantial degree of variability in the extent to which narcissism (as measured by the Narcissistic Personality Inventory or NPI; Emmons, 1987) and self-esteem (measured using a variety of self-report scales) are associated. Data from 329 college students provided support for the hypothesis that the variability in associations between narcissism and different measures of self-esteem may be explained in part by the degree to which a given self-esteem measure is related to dominance. These results have important implications for research on narcissism and self-esteem, as well as the broader issue of how self-esteem is conceptualized and measured in psychological research.     

Having less,giving more? Two preregistered replications of the relationship between social class and prosocial behavior

In the present report, we describe two planned direct replications of studies on the relationship between social class and prosocial behavior. In the original studies, individuals with higher socioeconomic status have been shown to behave less prosocially across a variety of domains. This finding continues to influence both research and the public debate on the psychological correlates of social class. At the same time, the validity of the original findings has been contested. Against this background, pre-registered direct replication studies with sufficient statistical power are warranted to test the robustness of these influential findings. We conducted two replication studies to provide valuable diagnostic information with regard to the relationship between social class and prosocial behavior. Our results indicate that the generalizability of the original findings may be much more limited than suggested. In addition, they highlight the need for an increased reliance on psychometrically established measures to facilitate cumulative research on the relationship between social class and prosocial behavior.     

Do people agree about the causes of behavior? A social relations analysis of behavior ratings and causal attributions

Two studies examined consistency and agreement in behavior ratings and causal attributions. In Study 1, participants (N = 280) engaged in a series of getting-acquainted conversations in one of 3 communication media (face-to-face, telephone, computer mediated); in Study 2, participants (N = 120) engaged in a competitive group task. In both studies, participants rated themselves and their interaction partners on a set of behaviors and then made attributions about the causes of those behaviors. The major findings were that (a) participants consistently favored some causal factors over others in explaining both their own and their partners' behavior, supporting the existence of generalized attributional styles; and (b) participants showed moderate self-partner and partner-partner agreement about behavior but virtually no agreement about the causes of behavior. Thus, in brief interactions people tend to see themselves and others through the lens of their stable patterns of perceiving and interpreting behavior.     

Are memory self-efficacy and memory performance related? A meta-analysis

The association between memory self-efficacy (MSE) and memory performance is highly documented in the literature. However, previous studies have produced inconsistent results, and there is no consensus on the existence of a significant link between these two variables. In order to evaluate whether or not the effect size of the MSE-memory performance relationship in healthy adults is significant and to test several theory-driven moderators, we conducted a meta-analysis of published and unpublished studies. A random-effects model analysis of data from 107 relevant studies (673 effect sizes) indicated a low but significant weighted mean correlation between MSE and memory performance, r = .15, 95% CI [.13, .17]. In addition, the mean effect size was significantly moderated by the way MSE was assessed. Memory performance was more strongly related to concurrent MSE (perceived current ability to perform a given task) than it was to global MSE (perceived usual memory ability in general). Furthermore, we found marginally larger MSE-memory performance correlations when the memory situations used to assess MSE involved familiar stimuli. No effect of the method used to assess global MSE or domain MSE (memory rating vs. performance predictions) was found. The results also show that the resource demands of the memory tasks have a moderator effect, as the MSE-performance correlation is larger with free-recall and cued-recall tasks than it is with recognition tasks. Limitations (generalization issues, moderators not considered) and implications for future research are discussed.     

Do young and older adults rely on different processes in source memory tasks? A neuropsychological study

Source memory has consistently been associated with prefrontal function in both normal and clinical populations. Nevertheless, the exact contribution of this brain region to source memory remains uncertain, and evidence suggests that processes used by young and older adults may differ. The authors explored the extent to which scores on composite measures of neuropsychological tests of frontal and medial temporal function differentially predicted the performance of young and older adults on source memory tasks. Results indicated that a frontal composite measure, consistently associated with source memory performance in older adults, was unrelated to source memory in young adults, although it was sensitive to a demanding working memory task. The memory composite score, however, predicted performance in the young group. In addition, item and source memory were correlated in young but not older people. Findings are discussed in terms of age-related differences in working memory and executive functions, and differential binding processes necessary for item and source memory. The requirement to integrate item and source information at encoding appears to place greater demands on executive or working memory processes in older adults than in younger adults.     

Experiences of justice in school and attitudes towards democracy: A matter of social exchange?

In a democratic society, school has the goal to foster democratic attitudes in students. Besides explicit attempts to do so, justice experiences in school may be crucial to develop positive attitudes towards democracy. Therefore, we studied the relationship between different dimensions of justice experiences in school and democratic attitudes. We further examined a potential mechanism underlying this relationship, namely general trust, and hypothesized that the relationship between justice experiences in school and democratic attitudes can be understood on the basis of social exchange theory. A total of 210 participants who had visited a public school gave information about their justice experiences in school, general trust, and democratic attitudes. First, it was shown that overall experiences of distributive and interactional justice predict democratic attitudes, more specifically the approval of civic and human rights and the approval of the democratic institutions. Second, we found that the relationships between overall distributive and interactional justice and the approval of civic and human rights, the approval of the democratic institutions, and the approval of democracy-supporting behaviors are each mediated by general trust which can be interpreted as a social exchange process. This study therefore highlights the role of general justice-related school experiences for the development of democratic attitudes.     

What do eye movements reveal about the role of memory in visual search?

Horowitz and Wolfe (1998, 2003) have challenged the view that serial visual search involves memory processes that keep track of already inspected locations. The present study used a search paradigm similar to Horowitz and Wolfe's (1998), comparing a standard static search condition with a dynamic condition in which display elements changed locations randomly every 111 ms. In addition to measuring search reaction times, observers' eye movements were recorded. For target-present trials, the search rates were near-identical in the two search conditions, replicating Horowitz and Wolfe's findings. However, the number of fixations and saccade amplitude were larger in the static than in the dynamic condition, whereas fixation duration and the latency of the first saccade were longer in the dynamic condition. These results indicate that an active, memory-guided search strategy was adopted in the static condition, and a passive “sit-and-wait” strategy in the dynamic condition.     

The role of part—whole information in reasoning about relative size

Models of comparative judgment have assumed that relative magnitude is computed from knowledge about absolute magnitude rather than retrieved directly. In Experiment 1, participants verified the relative size of part-whole pairs (e.g., tree-leaf) and unrelated controls (e.g., tree-penny). The symbolic distance effect was much smaller for part-whole pairs than for unrelated controls. In two subsequent experiments, participants determined either which of two objects was closer in size to a third object or which of two pairs had a greater difference in the size of its constituents. In contrast to the paired comparison task in Experiment 1, judgments of part-whole items were more sensitive to the influence of symbolic distance than were unrelated controls. The fact that the part-whole relation attenuates the effects of symbolic distance in a paired comparison task but not in tasks that require an explicit comparison of size differences suggests that the part-whole relation provides a source of information about relative magnitude that does not depend on knowledge about absolute magnitude.

Does the nature of the experience influence suggestibility? A study of children's event memory

Two experiments examined the effects of event modality on children's memory and suggestibility. In Experiment 1, 3- and 5-year-old children directly participated in, observed, or listened to a narrative about an event. In an interview immediately after the event, free recall was followed by misleading or leading questions and, in turn, test recall questions. One week later children were reinterviewed. In Experiment 2, 4-year-old children either participated in or listened to a story about an event, either a single time or to a criterion level of learning. Misleading questions were presented either immediately or 1 week after learning, followed by test recall questions. Five-year-old children were more accurate than 3-year-olds and those participating were more accurate than those either observing or listening to a narrative. However, method of assessment, level of event learning, delay to testing, and variables relating to the misled items also influenced the magnitude of misinformation effects.
