When the face fits: Recognition of celebrities from matching and mismatching faces and voices

The results of two experiments are presented in which participants engaged in a face-recognition or a voice-recognition task. The stimuli were face–voice pairs in which the face and voice were co-presented and were either “matched” (same person), “related” (two highly associated people), or “mismatched” (two unrelated people). Analysis in both experiments confirmed that accuracy and confidence in face recognition was consistently high regardless of the identity of the accompanying voice. However accuracy of voice recognition was increasingly affected as the relationship between voice and accompanying face declined. Moreover, when considering self-reported confidence in voice recognition, confidence remained high for correct responses despite the proportion of these responses declining across conditions. These results converged with existing evidence indicating the vulnerability of voice recognition as a relatively weak signaller of identity, and results are discussed in the context of a person-recognition framework.     

Constructivism and Family Therapy

Personal construct and family systems theories can profit from an exchange of ideas concerning the relationship between their personal and interpersonal aspects of construction. This article examines three possible points of contact between the two orientations. First, we suggest that personal construct psychology could profit from addressing the important contributions of the family context to the development of each individual's system. Second, we address the impact of the person's constructions on the larger family system. Third, we suggest that the family system itself develops a system of shared constructions that define and bind its identity and interactions. Each of these areas of interface carries implications for therapy, and specific intervention techniques corresponding to each of these are discussed.     

THE EFFECT OF ELICITATION METHODS ON PERSONAL CONSTRUCT DIFFERENTIATION AND VALENCE

The effect of personal construct elicitation methods on construct content and structure was addressed in two studies. In Study 1, a between-subjects design was used to compare Kelly's (1955) original Triadic Difference method of elicitation with a Dyadic Opposite method. Study 2 used a fully-crossed, mixed factorial design to compare Kelly's (1955) Triadic Difference method with Epting, Suchman, and Nickeson's (1971) Triadic Opposite method. Results showed that "difference" methods of construct elicitation produced significantly higher levels of construct differentiation, lower numbers of positive emergent construct poles, and less socially undesirable implicit construct poles than "opposite" methods (see also Caputi & Reddy, in press). Implications of these findings are discussed in relation to a critical reappraisal of repertory grid methods.     

A Review of: “International Handbook of Personal Construct Psychology”

Abstract

Constructivism is a relatively new development in the Brazilian psychological community. The dissemination of constructivist theory is difficult to trace, but can perhaps be best understood by looking at the development of Brazilian psychology and through tracing related theoretical movements like the cognitive-behavioral movement, which appears to have prepared the intellectual climate for constructivist principles. The growth of constructivism in Brazil is illustrated through the formation of constructivist organizations, a consideration of educational opportunities related to the theory, and a review of recent conferences where South American professionals could be exposed to constructivist ideas.     

Between-object binding and visual attention

Many previous studies have found that we can attend pairs of visual features (e.g., colour, orientation) more efficiently when they belong to the same “object” compared to when they belong to separate, neighbouring objects (e.g., Behrmann, Zemel, & Mozer, 1998; Egly, Rafal, & Driver, 1994). This advantage for attending features from the same object may reflect stronger binding between these features than arises for pairs of features belonging to separate objects. However, recent findings described by Davis, Welch, Holmes, and Shepherd (in press) suggest that under specific conditions this same-object advantage can be reversed, such that attention now spreads more readily between features belonging to separate neighbouring objects than between features of the same object. In such cases it would appear that features belonging to separate visual objects are more strongly bound than features of the same object. Here I review these findings and present the results of a new study. Together these data suggest that magnocellular processes in the human visual system bind together features from separate objects, whereas parvocellular processes bind together features from the same object.     

Enhancing Athletic Performance Using Digital Video in Consulting

Video has been used successfully in psychosocial interventions to help train communication skills, document behaviors, and as a feedback tool for behavior modification strategies. The need for equipment portability, together with editing expertise, has limited video use in sport psychology. Newer digital video systems help overcome these problems, meaning that sport psychologists can readily use this technology in the field. We discuss and provide experiential observations of how digital video can be used to improve player, coach, and team performance. Also reviewed are new consultation opportunities for sport psychologists with video skills. These new areas center on perceptual skills training and talent identification using perceptual skills testing.     

Interaction Between Visually and Kinesthetically Triggered Voluntary Responses

A voluntary motor response that is prepared in advance of a stimulus may be triggered by any sensory input. This study investigated the combination of visual and kinesthetic inputs in triggering voluntary torque responses. When a visual stimulus was presented alone, subjects produced a fast and accurate increase in elbow flexion torque. When a kinesthetic stimulus was presented instead of the visual stimulus, subjects produced a similar response with a reduced response latency. When a visual stimulus was presented in combination with a kinesthetic stimulus, subjects initiated their responses after either a visual or a kinesthetic response latency, depending on the relative timing of the two stimuli. An analysis of response amplitude suggested that when visual and kinesthetic stimuli were combined, both stimuli triggered a response. The results are more consistent with a simple behavioral model of addition of visual and kinesthetic responses (which predicts that the response to combined stimuli should be the sum of individual responses) than with a model of exclusion of one response (which predicts that the response to combined stimuli should be identical to either the visual or the kinesthetic response). Because addition of visually and kinesthetically triggered responses produced a response with an erroneously large amplitude, it is suggested that visual and kinesthetic inputs are not always efficiently integrated.     

Loneliness: Lost in the Landscape of Meaning

The present study is an examination of sex differences in the sources of annoyance that partners in close relationships might experience as a result of each other's behavior. To test hypotheses derived from S. E. Cross and L. Madson's (1997) self-construal theory and from D. M. Buss's (1989) evolutionary psychology-based model, men and women of varying ages and educational levels were asked to rate how annoyed they would be with each of 13 potentially annoying behaviors of their intimate partner. Results were consistent with self-construal theory in that relationship-threatening behaviors were more annoying to women than to men and autonomy threatening behaviors were more annoying to men than to women. Results were also consistent with evolutionary psychology in that aggressive behaviors were more annoying to women than to men and sexual withholding was relatively more annoying to men than to women. Sex differences in annoyance with relationship-threatening, autonomy-threatening, and reproductive strategy behaviors were independent of age and education level, although these factors did affect respondents' annoyance when partners were unemotional, sloppy, or pleased with their own appearance. Results showed that sources of annoyance in intimate relationships should not only be studied from an evolutionary perspective but from the perspectives of social, personality, and developmental psychology as well.     

Relationship of Maudsley Obsessional-Compulsive Inventory Subscales with Negative Priming

The relationship between the 4 subscales (Checking, Cleaning, Doubting, Slowness) and total score of the Maudsley Obsessional-Compulsive Inventory (MOCI) and performance in a negative-priming task and a response-speed task in 102 undergraduates was examined. Only Cleaning subscale performance correlated with magnitude of negative priming. Performance on the Checking, Slowing, and Doubting subscales was not significantly related to the magnitude of negative priming. The not significant correlation between Checking score and negative priming magnitude supports the findings of Maki, O'Neill, and O'Neill (1994), who observed that compulsive checking (of, e.g., whether the stove is turned off) appeared to be unrelated to deficiencies in inhibitory control. The present results are not, however, consistent with the view that obsessive-compulsive characteristics (as measured by the MOCI) result in a disruption in and a reduction of inhibitory control (Enright & Beech, 1993).     

Memory Drum Theory

Two experiments investigated the memory drum theory’s prediction (Henry & Rogers, 1960) that simple reaction time (SRT) increased with the complexity of the response to be initiated. Experiment 1 (N = 9) matched the Experiment 1, Group 1, SRT condition described by Henry and Rogers. Results of Experiment 1 replicated those of Henry and Rogers and indicated that the memory drum theory’s prediction of increased SRT as a function of increased complexity of response was tenable. Experiment 2 (N = 11) tested the effects of anatomical unit, extent, and target size on SRT, premotor time, and motor time. The results supported the contention that alternative explanations for SRT were possible. With complexity constant, increases in anatomical unit lead to increases in SRT, but only in the motor time component which indicated electromechanical rather than neuromotor program delays. It is proposed that the increased motor time could be explained by peripheral events such as the duration maximum torque must be applied by the agonist muscle(s) to generate the angular acceleration required to initiate rapid movement. SRT, premotor time, and motor time increased when target size was reduced from 6.35 cm to .79 cm. The increased premotor time could be a function of the determining of new equilibrium points for the elbow joint during response initiation. No effects on SRT were observed for extent.
