Does it matter how I perceive my nation? National symbols,national identification and attitudes toward immigrants

We examined how the ways of imagining one's own nation relate to the relationship between national identification and individuals’ attitudes towards immigrants. National imagination is studied through two types of national symbols representing the nation in terms of confrontation between groups (i.e., war and sports) and a unique entity (i.e., nature and traditional culture). We found that national identification was positively associated with the degree to which individuals perceived their nation through a historical war and sports, which, in turn, enhanced negative attitudes toward immigrants. Unexpectedly, the degree to which individuals perceived their nation through nature and traditional culture was positively associated with positive intergroup attitudes. The results emphasize that the degree to which individuals perceive their nation through different national symbols is an important factor for understanding intergroup relations.     

Individual differences in working memory capacity and episodic retrieval: examining the dynamics of delayed and continuous distractor free recall

Two experiments explored the possibility that individual differences in working memory capacity (WMC) partially reflect differences in the size of the search set from which items are retrieved. High- and low-WMC individuals were tested in delayed (Experiment 1) and continuous distractor (Experiment 2) free recall with varying list lengths. Across both experiments low-WMC individuals recalled fewer items than high-WMC individuals, recalled more previous list intrusions than high-WMC individuals, and recalled at a slower rate than high-WMC individuals. It is argued that low-WMC individuals' episodic retrieval deficits are partially due to the fact that these individuals search through a larger set of items than high-WMC individuals. Simulations based on a random search model were consistent with these general conclusions.     

Individual differences in recovery time from attentional capture

Working memory capacity reflects a core ability of the individual that affects performance on many cognitive tasks. Recent work has suggested that an important covariate of memory capacity is attentional control, and specifically that low-capacity individuals are more susceptible to attentional capture by distractors than high-capacity individuals are, with the latter being able to resist capture. Here, we tested an alternative account according to which all individuals are equally susceptible to attentional capture, but high-capacity individuals recover more quickly than low-capacity individuals. Using psychophysical and electrophysiological methods, we measured recovery time from attentional capture. In two experiments, we found that high- and low-capacity individuals showed equivalent attentional capture effects in the initial moments following capture, but that low-capacity individuals took much longer to recover than high-capacity individuals did. These results suggest that the poor attentional control associated with low capacity is due to slow disengagement from distractors.     

Transient Things and Permanent Stuff

A view of individuals as constituted of quantities of matter, both understood as continuants enduring over time, is elaborated in some detail. Constitution is a three-place relation which can't be collapsed to identity because of the place-holder for a time and because individuals and quantities of matter have such a radically different character. Individuals are transient entities with limited lifetimes, whereas quantities are permanent existents undergoing change in physical and chemical properties from time to time. Coincidence, considered as a matter of occupying the same place, is developed, alongside sameness of constitutive matter, as a criterion of identity for individuals. Quantities satisfy the mereological criterion of identity, applicable to entities subject to mereological relations and operations such as regions of space and intervals of time. A time-dependent analogue of mereological parthood is defined for individuals, in terms of which analogues of the other mereological relations can be defined. But it is argued that there is no analogue of the mereological operation of summation for individuals.     

Consociated Contemporaries as an Emergent Realm of the Lifeworld: Extending Schutz's Phenomenological Analysis to Cyberspace

According to the differences in the spatial-temporal co-location of human individuals, Alfred Schutz divided the contemporaneous lifeworld into two major realms: the realm of consociates made up of individuals sharing a community of space and a community of time, and the realm of contemporaries made up of individuals sharing neither a community of space nor a community of time. Extending Schutz's phenomenological analysis to cyberspace, this paper delineates an emergent third realm – the realm of consociated contemporaries, in which individuals share a community of time without sharing a community of space. A central argument of this paper is that the emergence of this social domain in cyberspace reconfigures the structure of the lifeworld by creating a new spatial-temporal condition of human contact, which gives rise to a new mode of human interaction and a new form of human relationship. The revolution of electronic communication is therefore a revolution of the ways in which human individuals come to construct we-relationships with one another in shared meaning contexts.     

Belief in a just world and social dominance orientation: Evidence for a mediational pathway predicting negative attitudes and discrimination against individuals with mental illness

Prejudice against individuals with mental illness stems from multiple factors, including the personality traits of those harboring the prejudiced attitudes. However, little is known about the personality processes (as opposed to static correlates) leading to negative attitudes and discrimination toward individuals with mental illness. The present research tested a mediational model in which negative attitudes against such people and resulting intentions to discriminate are distally rooted in just-world beliefs, which predispose people toward higher social dominance orientation, a well-known proximal personality predictor of general prejudice. Participants completed measures of behavioral intentions, attitudes toward individuals with mental illness, social dominance orientation, and belief in a just world. The proposed mediational model was supported, and an alternative causal model was not. These results illuminate the personality-process antecedents of attitudes toward individuals with mental illness and provide a foundation for research targeting interventions intended to reduce prejudice and discrimination against this population.     

Domains of Sciences,Universes of Discourse and Omega Arguments

Each science has its own domain of investigation, but one and the same science can be formalized in different languages with different universes of discourse. The concept of the domain of a science and the concept of the universe of discourse of a formalization of a science are distinct, although they often coincide in extension. In order to analyse the presuppositions and implications of choices of domain and universe, this article discusses the treatment of omega arguments in three very different formalizations of arithmetic. In Peano's formalization the domain is a restricted class of individuals, while the universe of discourse is the unrestricted class of all individuals. In Gödel's formalization the domain is a restricted class of individuals as in Peano's formalization, but the universe of discourse coincides with the domain. In Whitehead-Russell's formalization the domain is a class of logical notions in Tarski's sense, that are necessarily not individuals, whereas the universe of discourse is the unrestricted class of individuals as in Peano's formalization. The present approach emphasizes the viewpoint that the universe of discourse of a given discourse is important in determining which propositions are expressed by which sentences.     

Is there a place for individual subjectivity within a social constructionist epistemology?

The epistemological turn towards social constructionism has become well established within the field of family systemic therapy. Social constructionism has provided therapists with a theoretical rationale for the concentration upon the social context within which individuals and families live their lives. This is a philosophical position that pushes to the margins the positivist premise that individuals have fixed and measurable personalities in favour of a discourse which proposes that the person is encountered differently within different social contexts. Prompted by the growing interest in systemic practice with individuals and by the rediscovery of the psychoanalytic canon within family therapy literature, the adequacy of this position is examined and an attempt is made to open up a space within social constructionist discourse for a theory of individual subjectivity. Findings from a research project are the starting point for this venture. These findings are understood through the lens of psychoanalytic theory, with particular reference to the work of Jacques Lacan.     

Individual versus group discontinuity: The role of intergroup contact

Following earlier demonstrations of more competitiveness between groups than between individuals in the context of a PDG matrix, two additional conditions were studied. These were a group-all condition in which the intergroup contact involved all the members in both groups (rather than just representatives as in the previously studied group-representative condition), and an interdependence condition in which physically separated individuals shared their winnings with the other subjects on the same side of the suite of rooms (rather than neither giving winnings to nor receiving winnings from other such subjects as in the previously studied individuals condition). The results indicated that there was a large overall tendency for the group-representative and group-all conditions to be more competitive than the individuals and interdependence conditions, that the group-representative condition was more competitive than the group-all condition, and that the interdependence condition and individuals condition did not differ. The difference between the group-representative and group-all condition was interpreted as consistent with a prediction that intergroup contact can reduce competitiveness even when there is conflict and the absence of norms requiring cooperative behavior. The lack of difference between the interdependence condition and the individuals condition was interpreted as inconsistent with an altruisticrationalization hypothesis according to which group members rationalize their competitiveness toward the other group as being enacted for the sake of fellow group members.     

The disintegrative factor in therapeutic groups as illuminated by kibbutz life

This article deals with the way individuals cope with the threat they experience in the framework of psychodynamic group psychotherapy. This threat, which is understood to be a disintegrative threat, is intensified in the therapeutic group. We see the therapeutic group as possessing attributes of a potential space, in which the participants are enabled to process the defense and coping mechanisms intended to preserve the sense of integration. This will be illustrated by the experiences of individuals who grew up in a kibbutz (an Israeli society in which infants were raised with their peer group) and participated in psychodynamic groups.     

孤独症谱系障碍者的生物运动探测障碍：基于行为与神经的证据

关于孤独症谱系障碍个体探测生物运动的能力是否受损,已有行为研究尚存分歧。导致分歧的原因可能是实验刺激、实验任务和测量指标存在差异。然而,神经研究却一致证实其潜在的神经机制存在异常。领域特殊性观点认为该障碍可能是基于后侧颞上沟功能异常的社会性功能障碍,也可能是基于镜像神经元功能异常的社会性功能障碍;而领域一般性观点认为该障碍可能是基于背侧视觉流功能异常的视运动知觉障碍,也可能基于脑功能联结异常的弱中央统合障碍。据此,本文将从研究范式、行为表现及潜在机制三个方面梳理相关研究,以期为后续研究提供新方向。     

Body size over-estimation in women with anorexia nervosa is not qualitatively different from female controls

Over-estimation of body size is a cardinal feature of anorexia nervosa (AN), usually revealed by comparing individuals who have AN with non-AN individuals, the inference being that over-estimation is pathological. We show that the same result can be reproduced by sampling selectively from a single distribution of performance in body size judgement by comparing low BMI individuals with normal BMI individuals. Over-estimation of body size in AN is not necessarily pathological and can be predicted by normal psychophysical biases in magnitude estimation. We confirm this prediction in a dataset from a morphing study in which 30 women with AN and 137 control women altered a photograph of themselves to estimate their actual body size. We further investigated the relative contributions of sensory and attitudinal factors to body-size overestimation in a sample of 166 women. Our results suggest that both factors play a role, but their relative importance is task dependent.     

Everyday executive function in standard-risk acute lymphoblastic leukemia survivors

Although absolute pitch (AP) is a rare skill in typical development, individuals with Williams syndrome (WS) are often referred to as possessing this musical ability. However, there is paucity of research on the topic. In this article, 2 studies were conducted to evaluate AP in WS. In Study 1, seven musically trained individuals with WS, 14 musically trained typically developing controls matched for chronological age, and 2 experienced musicians with AP completed a pitch-identification task. Although the task was a classical assessment of AP, it required participants to have musical knowledge, and the availability and accessibility of musically trained individuals with WS is very low. In Study 2, a paradigm suitable for evaluating AP in individuals without musical training was used, which made it possible to evaluate a larger group of participants with WS. A pitch memory test for isolated tones was presented to 27 individuals with WS, 54 typically developing peers matched for chronological age, and the 2 musicians with AP. Both individuals with WS and their controls obtained low results in the two studies. They showed an arbitrary pattern of response, and their performance was far from that of musicians with AP. Therefore, participants with WS did not appear to possess AP. Unlike what is usually claimed, results suggest that AP is not a remarkable ability in WS and that, as in the typically developing population, this musical ability is also rare in individuals with WS.     

Mood-congruent free recall bias in anxious individuals is not a consequence of response bias

The status of mood-congruent free recall bias in anxious individuals was evaluated following incidental encoding of target words. Individuals with high and low levels of trait anxiety completed a modified Stroop task, which revealed an attentional bias for threat-related stimuli in anxious individuals. This group was significantly slower in naming the colour in which threat-related words were displayed compared to neutral words. In a subsequent free recall test for the words used in the modified Stroop task, anxious individuals recalled more threat-related words compared to low-anxious people. This difference was significant even when controlling for the false recall of items that had not been presented during study. These results support the view put forward by Russo, Fox, Bellinger, and Nguyen-Van-Tam (2001) that mood-congruent free recall bias in anxious individuals can be observed if the target material is encoded at a relatively shallow level. Moreover, contrary to Dowens and Calvo (2003), the current results show that the memory advantage for threat-related information in anxious individuals is not a consequence of response bias.     

Components of attentional bias to threat in high trait anxiety: Facilitated engagement, impaired disengagement, and attentional avoidance

There is a wealth of evidence demonstrating enhanced attention to threat in high trait anxious individuals (HTA) compared with low trait anxious individuals (LTA). In two experiments, we investigated whether this attentional bias is related to facilitated attentional engagement to threat or difficulties disengaging attention from threat. HTA and LTA undergraduates performed a modified exogenous cueing task, in which the location of a target was correctly or incorrectly cued by neutral, highly and mildly threatening pictures. Results indicate that at 100 ms picture presentation, HTA individuals more strongly engaged their attention with and showed impaired disengagement from highly threatening pictures than LTA individuals. In addition, HTA individuals showed a stronger tendency to attentional avoidance of threat at the 200 and 500 ms picture presentation. These data provide evidence for differential patterns of anxiety-related biases in attentive processing of threat at early versus later stages of information processing.     

Musically tone-deaf individuals have difficulty discriminating intonation contours extracted from speech

Musically tone-deaf individuals have psychophysical deficits in detecting pitch changes, yet their discrimination of intonation contours in speech appears to be normal. One hypothesis for this dissociation is that intonation contours use coarse pitch contrasts which exceed the pitch-change detection thresholds of tone-deaf individuals (). We test this idea by presenting intonation contours for discrimination, both in the context of the original sentences in which they occur and in a "pure" form dissociated from any phonetic context. The pure form consists of gliding-pitch analogs of the original intonation contours which exactly follow their pattern of pitch and timing. If the spared intonation perception of tone-deaf individuals is due to the coarse pitch contrasts of intonation, then such individuals should discriminate the original sentences and the gliding-pitch analogs equally well. In contrast, we find that discrimination of the gliding-pitch analogs is severely degraded. Thus it appears that the dissociation between spoken and musical pitch perception in tone-deaf individuals is due to a deficit at a higher level than simple pitch-change detection.     

Mood-congruent free recall bias in anxious individuals is not a consequence of response bias

The status of mood-congruent free recall bias in anxious individuals was evaluated following incidental encoding of target words. Individuals with high and low levels of trait anxiety completed a modified Stroop task, which revealed an attentional bias for threat-related stimuli in anxious individuals.

In a subsequent free recall test for the words used in the modified Stroop task, anxious individuals recalled more threat-related words compared to low-anxious people.

Variation in working memory capacity and episodic memory: Examining the importance of encoding specificity

In the present study, we examined the extent to which encoding specificity influences the relation between individual differences in working memory capacity (WMC) and episodic recall. Participants performed a paired associates cued recall task in which a rhyme or a semantic judgment was made during encoding. During recall participants were presented with the cue word along with either a rhyme or semantic cue. Across both rhyme and semantic conditions, encoding and retrieval conditions either matched or mismatched. When encoding and retrieval conditions matched, high WMC individuals outperformed low WMC individuals. When encoding and retrieval conditions mismatched, high and low WMC individuals performed equivalently. Importantly, this occurred because high WMC individuals were hurt more than low WMC individuals when conditions mismatched. These results demonstrate the importance of encoding specificity in the relation between WMC and episodic recall as well as of unifying prior work that has demonstrated that high WMC individuals are hurt more in some recall conditions than are low WMC individuals.     

Fear generalisation in individuals with high neuroticism: increasing predictability is not necessarily better

Fear generalisation, a process by which conditioned fear spreads to similar but innocuous stimuli, is key in understanding why some individuals feel unsafe in objectively non-threatening situations. Both trait neuroticism and lack of predictability about the likelihood of feared consequences are associated with negative affect in the face of ambiguity and may increase the degree to which fear generalises. Undergraduates (N?=?129) with varying degrees of neuroticism were randomised to either high- or low-instructional predictability conditions prior to fear acquisition. A fear generalisation test measured risk ratings and attentional bias on a modified dot-probe paradigm. Among individuals with higher neuroticism, providing instructional predictability did not reduce fear; these individuals reported higher risk and increased attentional bias toward ambiguous stimuli. Overall, for individuals with higher neuroticism, predictability information hurt rather than helped interpretation of ambiguous stimuli, challenging a common conceptualisation of predictability as a factor that reduces fear.
