Visual search for dimensionally redundant pop-out targets: parallel-coactive processing of dimensions is location specific

Three visual search experiments investigated redundancy gains for single and dual odd-one-out feature targets that differed from distractors in orientation, color, or both. In Experiment 1, redundant-target displays contained (a) a single target defined in 2 dimensions, (b) dual targets each defined in a different dimension, or (c) dual targets both defined in the same dimension. The redundancy gains, relative to single nonredundant targets, decreased from the first condition on, with violations of J. Miller's (1982) race model inequality (RMI) manifested only in the first 2 conditions. Experiment 2 systematically varied the spatial separation between dual targets each defined in a different dimension. Violations of the RMI were evident only when the 2 targets occupied nearby locations. Experiment 3 provided evidence of RMI violations by dimensionally redundant targets at both precued (likely) and noncued (unlikely) display locations. Taken together, these results suggest that there is coactivation of a common mechanism by target signals in different dimensions (not by signals in the same dimension), that the coactivation effects are spatially specific, and that the coactivated mechanisms are located at a preattentive, perceptual stage of processing.     

Context-Dependent Emotion Regulation: Suppression and Reappraisal at the Burning Man Festival

Two studies investigated the combined effects of cultural practices, ancestry, and phenotype on ethnic categorization and the distribution of resources to minorities. Perceivers formed impressions of Latino internship candidates who varied in Spanish language fluency, White/European ancestry, and skin color. Spanish fluency influenced the distribution of minority resources to all targets, but only influenced the Latino categorization of targets who had White/European ancestry. The effect of Spanish fluency on minority resource distribution was explained by the White/European target's Latino categorization and perceived commitment to minority communities. We discuss why factors beyond racial/ethnic categorization may matter in minority resource distribution decisions.     

The capacity to symbolise: Ideas and implications

Through a literature review and clinical examples of session material and dreams, this paper explores aspects of the origin and development of the capacity to symbolise. The literature review considers Freud’s thinking on symbols in dreams, hysteria and obsessional neurosis, Klein’s discovery of the importance of unconscious phantasy, Bion’s ideas on the psychotic part of the mind and Bick’s seminal ideas on skin as an important symbolic boundary between psyche and soma. The clinical material in this paper is used to demonstrate the capacity to symbolise, reasons for the impairment of this capacity, and how the translation of symbols through interpretation in a therapeutic setting can enable the symbols to acquire meaning. It includes examples both of the author’s work with adults and of other clinicians’ work with a child and an adolescent in a psychotic state of mind. The paper’s aim is to consolidate the idea that the capacity to symbolise grows out of an optimal early parent/child relationship and that the awareness of the significance of the symbols when they have been interpreted is of crucial importance.     

The underutilization of applied psychology

Abstract

The utilization of social science and in particular of applied psychology is a complex process, beset with obstacles. Five approaches to gathering knowledge are described and a conceptually important distinction is made between Action-Research and Research-Action. The paper analyses a number of obstacles to utilization from the point of view of the research community, the potential user and the academic institutions which support the work. Evidence in relation to five barriers to application is used to identify a tentative model of underutilization.     

123s and ABCs: developmental shifts in logarithmic‐to‐linear responding reflect fluency with sequence values

When placing numbers along a number line with endpoints 0 and 1000, children generally space numbers logarithmically until around the age of 7, when they shift to a predominantly linear pattern of responding. This developmental shift of responding on the number placement task has been argued to be indicative of a shift in the format of the underlying representation of number (Siegler & Opfer, 2003 ). In the current study, we provide evidence from both child and adult participants to suggest that performance on the number placement task may not reflect the structure of the mental number line, but instead is a function of the fluency (i.e. ease) with which the individual can work with the values in the sequence. In Experiment 1, adult participants respond logarithmically when placing numbers on a line with less familiar anchors (1639 to 2897), despite linear responding on control tasks with standard anchors involving a similar range (0 to 1287) and a similar numerical magnitude (2000 to 3000). In Experiment 2, we show a similar developmental shift in childhood from logarithmic to linear responding for a non‐numerical sequence with no inherent magnitude (the alphabet). In conclusion, we argue that the developmental trend towards linear behavior on the number line task is a product of successful strategy use and mental fluency with the values of the sequence, resulting from familiarity with endpoints and increased knowledge about general ordering principles of the sequence.A video abstract of this article can be viewed at: http://www.youtube.com/watch?v=zg5Q2LIFk3M     

A Path of Counselor Self‐Awareness

This article explores self‐reflection and self‐awareness from an ethical standpoint, proposing that counselors have a responsibility to themselves, their clients, and the profession to engage in these practices. The authors propose a path to counselor self‐awareness and a 2nd process that assumes counselor mastery.     

Haptic dominance in form perception: vision versus proprioception.

An experiment placed vision and touch in conflict by the use of a mirror placed perpendicular to a letter display. The mirror induced a discrepancy in direction and form. Subjects touched the embossed tangible letters p, q, b, d, W, and M, while looking at them in a mirror, and were asked to identify the letters. The upright mirror produced a vertical inversion of the letters, and visual inversion of the direction of finger movement. Thus, subjects touched the letter p, but saw themselves touching the letter b in the mirror. There were large individual differences in reliance on the senses. The majority of the subjects depended on touch, and only one showed visual dominance. Others showed a compromise between the senses. The results were consistent with an attentional explanation of intersensory dominance.
