On the examination couch: the relationship between the egocentric perspective and the attentional focus

Determined by anatomical characteristics, the binocular visual field has an elliptical shape. Whereas the focus of attention – that area of the visual field in which objects can be consciously perceived – is significantly smaller, its shape is not necessarily dependent on the same factors. Indeed, it is yet unknown if the maximum extents of the attentional focus’ meridians are dimensionally stable or adapt to the egocentric perspective. In this study, we intended to measure the expansion up to which peripheral stimuli can still be perceived while participants were sitting and lying on the left and on the right body side. Results demonstrate that contrary to the visual field the maximum extents along the attentional focus’ meridians remain stable across different head positions with a greater horizontal than vertical alignment. This indicates that the expansion ratios of the meridians of the attentional focus are not dependent on the egocentric perspective. Rather, they appear stable in space and gravity-based. Findings are discussed in terms of our visual environment and current as well as alternative interpretations are weighed against each other.     

Holistic Information Integration in Child Decision Making

Weighted‐additive (WADD) strategies require decision makers to integrate multiple values weighted by their relevance. From what age can children make choices in line with such a WADD‐strategy? We compare multi‐attribute decisions of children (6–7; 8–10; 11–12‐year‐olds) with adults in an open information‐board environment without pre‐decisional information search. In two experiments, we classify decision strategies based on individual choice patterns and find that in all age groups the majority of participants are users of a WADD‐strategy. Simple decision heuristics such as lexicographic strategies were applied rarely by children and not at all by adults. In two additional follow‐up studies, we further investigate the underlying process of WADD‐application by analysing decision latencies in combination with a retrospective think‐aloud study. Results suggest that children did not apply WADD‐strategies in a deliberate fashion in our experiments. Overall, our findings demonstrate that the ability to make good and quick decisions by holistically integrating information is already present in young children.

Rational Choice,Personality, and HIV‐Preventive Behavior in the Presence of Opportunities1

In this paper, condom use or non‐use in sexual intercourse with casual partners is analyzed on the basis of ideas derived from the theory of planned behavior (Ajzen & Madden, 1986), which is combined with the general theory of crime (Gottfredson & Hirschi, 1990). An integrated model allows the assumption that persons who display low self‐control are likely to seek out opportunities to engage in sexual intercourse with casual partners and are likely to display attitudes and subjective norms favoring the non‐use of condoms. The study consists of an empirical examination of these assumptions. A standardized questionnaire (vignette technique) was presented to a quota sample of 837 German adults aged 18 to 65 years. Loglinear analyses were carried out to examine the integrative model. The results are discussed with regard to the effectiveness of the theoretical framework applied and with regard to previous research that has been conducted in this area.     

Beurteilungsgrundlagen psychodynamischer Diagnostik

In the period of 1988–1999 752 anamnestic reports made by psychoanalysts-in-training on the basis of initial interviews with treatment seeking patients were examined concerning their psychodynamical judgement criteria. The study was conducded at the Institut für Psychotherapie e.V. in Berlin. Trained raters analysed first the presented “psychodynamic considerations” concerning their implicit theoretical and clinical concepts and second the supervising analysts commentaries. Moreover, the supervising analysts were asked to explicate their own theoretical orientation. The findings were then put in comparison. In the course of the study, changes over time in preferences for some concepts and diagnoses were observable. Psychoanalysts-in-training differ from experienced psychoanalysts in their preferred data sources, and men and women differ in their diagnoses. Concerning their theoretical orientation, psychoanalysts-in-training lean on their instructors.     

Flexible and inflexible task sets: asymmetric interference when switching between emotional expression, sex, and age classification of perceived faces

The present study investigated whether the processing characteristics of categorizing emotional facial expressions are different from those of categorizing facial age and sex information. Given that emotions change rapidly, it was hypothesized that processing facial expressions involves a more flexible task set that causes less between-task interference than the task sets involved in processing age or sex of a face. Participants switched between three tasks: categorizing a face as looking happy or angry (emotion task), young or old (age task), and male or female (sex task). Interference between tasks was measured by global interference and response interference. Both measures revealed patterns of asymmetric interference. Global between-task interference was reduced when a task was mixed with the emotion task. Response interference, as measured by congruency effects, was larger for the emotion task than for the nonemotional tasks. The results support the idea that processing emotional facial expression constitutes a more flexible task set that causes less interference (i.e., task-set "inertia") than processing the age or sex of a face.     

Trust my face: cognitive factors of head fakes in sports

In many competitive sports, players try to deceive their opponents about their behavioral intentions by using specific body movements or postures called fakes. For example, fakes are performed in basketball when a player gazes in one direction but passes or shoots the ball in another direction to avert efficient defense actions. The present study aimed to identify the cognitive processes that underlie the effects of fakes. The paradigmatic situation studied was the head fake in basketball. Observers (basketball novices) had to decide as quickly as possible whether a basketball player would pass a ball to the left or to the right. The player's head and gaze were oriented in the direction of an intended pass or in the opposite direction (i.e., a head fake). Responding was delayed for incongruent compared to congruent directions of the player's gaze and the pass. This head fake effect was independent of response speed, the presence of a fake in the immediately preceding trial, and practice with the task. Five further experiments using additive-factors logic and locus-of-slack logic revealed a perceptual rather than motor-related origin of this effect: Turning the head in a direction opposite the pass direction appears to hamper the perceptual encoding of pass direction, although it does not induce a tendency to move in the direction of the head's orientation. The implications of these results for research on deception in sports and their relevance for sports practice are discussed.     

Assortative mating in morningness-eveningness

Individuals differ in their morningness-eveningness preference (circadian preference); that is, some prefer morning hours for intellectual and physical activities and others prefer late afternoon or evening hours. This has been viewed as an interesting facet of personality. Assortative mating has been studied in personality research, but assortative mating in circadian preference has rarely been examined. Eighty-four couples participated in this study. They filled in the Composite Scale of Morningness; they also supplied data about rise times and bedtimes as well as information about relationship satisfaction and duration. The results revealed a moderate positive relationship between couple partners in morningness-eveningness which persisted after correcting for age. Similarly, correlations existed between the sleep-wake variables (rise time and bedtime) on weekdays and on the weekends, the association being higher for weekends. There was no significant correlation between length of the relationship and dissimilarity in morningness-eveningness, suggesting that the above-reported correlations reflect an initial assortment rather than convergence effects. Further, no significant correlation was found between dissimilarity in morningness-eveningness and relationship satisfaction. The results suggest that assortative mating in morningness-eveningness is likely and is probably based on an initial assortment. The likelihood to meet and mate may also be linked to chronotype. When differences in circadian preferences exist between possible partners, this reduces the likelihood that these persons meet either by accident or during work and leisure activities. Therefore, two extreme chronotypes are unlikely to meet each other because they have the smallest overlap in their preferred active time during the day due to the circadian rhythmicity.     

Attentional effects of negative faces: Top-down contingent or involuntary?

Recent research has substantiated that schematic negative faces are found more efficiently than positive faces among crowds of distractor faces of varying set sizes. The present study asks whether this relative search asymmetry (RSA) is intention driven or due to involuntary attentional capture. To that aim, participants were first tested in a condition in which negative and positive faces were searched for, and then in a condition in which negative or positive schematic faces appeared at chance level at the position of the target (valid trials) or of a distractor (invalid trials), the faces thus being task irrelevant (the 1/n paradigm). The expected search benefit for valid negative-face target trials most clearly occurred when participants searched for a target defined by a conjunction of color and position; when the target was defined either by an orientation or color singleton, we found rather weak or no evidence for involuntary attention capture by negative faces. We see the results as being (1) evidence that the RSA is partly based on stimulus-driven factors that occur independently of the intention to search for a positive or negative face, and (2) consistent with the assumption that the effects are mainly due to a more efficient rejection of positive-face than of negative-face distractors, rather than being due to attentional capture by the target
