The scope and generality of self-other asymmetry. In person perception

The present study was designed to investigate systematically various explanations focusing on information bias, information-processing bias, self-determination, false-consensus bias, quest for positive regard, and self-presentation strategies, that have been suggested for the Jones—Nisbett (1971) proposition that people describe their own behaviour as relatively more influenced by situational factors as compared to the actions of others. To test the scope and generality of this self—other asymmetry, a new methodology was introduced. Using Stimulus-Response Inventories of Hostility and Friendliness, the effects of different degrees of familiarity with target persons, of positivity—negativity of behaviours, and of the public—private nature of the rating context, were studied. Generalizability coefficients were used as indices for a dispositional and a situationist view on personality. The results support only explanations in terms of information-processing bias and self-determination strivings. Implications of this finding for the conceptualization of self-judgments and other-judgments are discussed.     

The Initial Interview with Diverse Populations: An Introduction to the Special Issue

Every initial clinical interview is a unique encounter between psychotherapist and client. This unique encounter typically includes interactions designed to build the therapeutic relationship, collect assessment data, develop a case formulation, and initiate psychotherapy. As the United States population has become more diverse, conducting an effective initial interview has become more complex and challenging. To meet this challenge, it is recommended that psychotherapists make cultural adaptations by seeking self-awareness, acquiring knowledge, and learning culture-specific techniques. This special issue includes six articles designed to stretch the way psychotherapists think about the initial interview and infuse greater multicultural sensitivity and humility into psychotherapy practice.     

Development of a Short Version of the Dutch Version of the Spielberger STAI Trait Anxiety Scale in Women Suspected of Breast Cancer and Breast Cancer Survivors

The objective of the current study was to develop a short form of the Dutch version of the State-Trait Anxiety Inventory (STAI) Trait scale and to provide initial validation data in a sample of breast cancer patients and survivors. This short trait anxiety (A-Trait) scale was designed to reduce time and effort required of severely ill or handicapped patients involved in extensive assessment procedures. Another goal was to assess A-Trait with minimal overlap with content that reflects Quality of Life (QoL) and fatigue. Three groups of women either completed the original Trait scale (Groups 1 and 2) or the 10-item trait version (Group 3). In Group 1, exploratory factor analysis with the Scree test, Velicer’s MAP criteria and parallel analysis as tests for factor retention, indicated a 10-item Trait version reflecting two factors: Anxiety Present and Anxiety Absent. In the other groups, confirmatory factor analysis showed that the two-factor short form provided the best fit. In all three groups Trait Anxiety was highly related to Neuroticism. The correlation between Overall QoL and General Health and the Anxiety Present short scale was lower than the correlation between Overall QoL and General Health and the full form (Z = 2.20, p = .03). With this short A-Trait scale it becomes possible to study the relationship between dispositional anxiety and clinically important outcome variables without inflating estimates of these relations through psychometric contamination.     

Seasonal Variations in Color Preference

We investigated how color preferences vary according to season and whether those changes could be explained by the ecological valence theory (EVT). To do so, we assessed the same participants’ preferences for the same colors during fall, winter, spring, and summer in the northeastern United States, where there are large seasonal changes in environmental colors. Seasonal differences were most pronounced between fall and the other three seasons. Participants liked fall‐associated dark‐warm colors—for example, dark‐red, dark‐orange (brown), dark‐yellow (olive), and dark‐chartreuse—more during fall than other seasons. The EVT could explain these changes with a modified version of Palmer and Schloss’ (2010) weighted affective valence estimate (WAVE) procedure that added an activation term to the WAVE equation. The results indicate that color preferences change according to season, as color‐associated objects become more/less activated in the observer. These seasonal changes in color preferences could not be characterized by overall shifts in weights along cone‐contrast axes.     

A Simple Method for Comparing Complex Models: Bayesian Model Comparison for Hierarchical Multinomial Processing Tree Models Using Warp-III Bridge Sampling

Psychometrika - Multinomial processing trees (MPTs) are a popular class of cognitive models for categorical data. Typically, researchers compare several MPTs, each equipped with many parameters,...     

Cerebellar structure and function: making sense of parallel fibers

Many parts of the brain have to cooperate in a finely tuned way in order to generate coordinated motor output. Parameters of these cooperations are adjusted during early childhood development and years of motor learning later in life. The cerebellum plays a special role in the concert of these brain structures. With the unusual geometrical arrangement of its neuronal elements, especially of parallel fibers and Purkinje cells the cerebellum is a selective and sensitive detector of a specific class of spatio-temporal activity patterns in the mossy fiber system: sequences of excitatory input which 'move' along the direction of parallel fibers at about 0.5 m/s, i.e. the speed of spike conductance in parallel fibers. Precise spatio-temporal neuronal activity patterns have been shown to occur in two major sources of afference to the cerebellum, the neocortex and the sensory feedback system. Based on our own experimental work and the above-mentioned findings we suggest that the cerebellum detects specific spatio-temporal activity patterns which trigger learned cerebellar output related to motor control and which contributes to the control of precise timing of muscle contraction.     

The role of shape recognition in figure/ground perception in infancy

In this study we sought to determine whether infants, like adults, utilize previous experience to guide figure/ground processing. After familiarization to a shape, 5-month-olds preferentially attended to the side of an ambiguous figure/ground test stimulus corresponding to that shape, suggesting that they were viewing that portion as the figure. Infants’ failure to exhibit this preference in a control condition in which both sides of the test stimulus were displayed as figures indicated that the results in the experimental condition were not due to a preference between two figure shapes. These findings demonstrate for the first time that figure/ground processing in infancy is sensitive to top-down influence. Thus, a critical aspect of figure/ground processing is functional early in life.     

Dichotomous perception of animal categories in infancy

ABSTRACT

Although there is a wealth of knowledge on categorization early in life, there are still many unanswered questions about the nature of category representation in infancy. For example, it is unclear whether infants are sensitive to boundaries between complex categories, such as types of animals, or whether young infants exhibit such sensitivity without explicit experience in the lab. Using a morphing technique, we linearly altered the category composition of images and measured 6.5-month-olds’ attention to pairs of animal faces that either did or did not cross the categorical boundary, with the stimuli in each pair being equally dissimilar from one another across the two types of image pairs. Results indicated that infants dichotomize the continua between cats and dogs and between cows and otters, but only when the images are presented in their canonical, upright orientations. These findings demonstrate a propensity to dichotomize early in life that could have implications for social categorizations, such as race and gender.     

Jihad Revisited

This article offers an overview of the various formulations of jihad during the first six Islamic centuries (7th–13th CE), showing them to be embedded in particular socio‐historical contexts. If the essential significance of jihad as righteous cause (i.e., action for the sake of a moral order) is shown to have been variously altered according to the needs and conditions of the Muslim community, significant possibilities arise for a contemporary understanding of jihad that is relevant to the needs and circumstances of the Muslim community today. Some features of the jihad tradition, although specific to a particular period and with little relevance today, continue to inform the current discussion on jihad. Discussion of the jihad tradition, then, should take care to distinguish the historically incidental features of the tradition from those with an enduring relevancy. By doing so, the jihad tradition will be able to contribute to discussions on the relation of religion to the public order and political organization, even those not limited to Islam.
