Toddlers can adaptively change how they categorize: same objects,same session,two different categorical distinctions

Two experiments demonstrate that 14‐ to 18‐month‐old toddlers can adaptively change how they categorize a set of objects within a single session, and that this ability is related to vocabulary size. In both experiments, toddlers were presented with a sequential touching task with objects that could be categorized either according to some perceptually salient dimension corresponding to a taxonomic distinction (e.g. animals vs. vehicles) or to some less obvious dimension (e.g. rigid vs. deformable). In each experiment, children with larger productive vocabularies responded to both dimensions, showing evidence of sensitivity to each way of categorizing the items. Children with smaller productive vocabularies attended only to the taxonomically related categorical grouping. These experiments confirm that toddlers can adaptively shift the basis of their categorization and highlight the dynamic interaction between the child and the current task in early categorization.     

Words, hemispheres, and processing mechanisms: A response to Marsolek and Deason (2007)

Ellis, Ansorge and Lavidor (2007) [Ellis, A.W., Ansorge, L., & Lavidor, M. (2007). Words, hemispheres, and dissociable subsystems: The effects of exposure duration, case alternation, priming and continuity of form on word recognition in the left and right visual fields. Brain and Language, 103, 292–303.] presented three experiments investigating the effects of exposure duration and format (normal vs mixed or alternating case) on the recognition of words presented in the left and right visual fields. The experiments were conducted within the framework of ‘dissociable neural subsystems theory’ developed by Marsolek and colleagues. Marsolek and Deason (2007) [Marsolek, C.J. & Deason, R.G. (2007). Hemispheric asymmetries in visual word-form processing: Progress, conflict, and evaluating theories. Brain and Language, 103, 304–307.] offer some reflections on our paper, including alternative interpretations of some of our findings. We respond to those reflections in this reply.     

Does selecting one visual object from several require inhibition of the actions associated with nonselected objects?

Four experiments are described in which 1 visual object (the target) was selected from another (the distractor) according to its color (Experiments 1, 2, and 4) or its relative location (Experiment 3) and then was classified according to a simple geometric property. Object classification was signaled as fast as possible by a precision or power grip response, and this grip was either compatible or incompatible with either object. When targets were selected by color, target-compatible grip responses were facilitated, but distractor-compatible grip responses were impaired. When targets were selected by location, similar results were obtained for target-compatible grip responses, but not distractor-compatible grip responses. These data are explained in terms of the involvement of action codes in object-level selection.     

Color preferences according to gender and sexual orientation

The present study was undertaken to verify findings surrounding sex differences in color preferences, and to extend this realm of inquiry by looking for possible differences in color preferences associated with sexual orientation. Based on a large sample of North American college students, significant gender differences were found, with the main difference being a greater preference for shades of blue by males than by females. Females, on the other hand, tended to be more evenly divided than males between preferring both green and blue. Regarding sexual orientation, we found no significant differences between heterosexuals and homosexual/bisexuals of either gender. In other words, male and female homosexuals/bisexuals exhibited essentially the same configuration of color preferences as did their heterosexual counterparts.     

Rational Emotive Behavior Therapy (REBT) in the New Millenium: A Cross-Cultural Approach

This paper reviews and discusses the results of five cross-cultural studies in Colombia, Costa Rica, El Salvador, Spain, and USA, using 2 (college students vs. their parents) × 2 (males vs. females) MANOVA match group designs with the Attitudes and Beliefs Inventory subscales as dependent variables, two multicultural studies investigating the relationship between some demographic variables (Pan American Health Organization's Index of Violence, and Acculturation) and people's Irrationality, and two multidisciplinary studies on the relationship between some medical conditions (skin diseases, and severity of symptoms during menopause) and Irrational Beliefs.     

Rational-emotive therapy applied to relationship therapy

RET is a comprehensive mode of relationship therapy that takes a double-barreled psychotherapeutic approach of helping all the partners in a relationship to accept responsibility for their own disturbances and failings and to work at correcting these-while, at the same time, helping them to understand and work actively at changing the marital or family system in which they are relating and the conditions in this system that are contributing to their practical and emotional problems. Rational-emotive relationship therapy is a form of cognitive behavior therapy that includes the following features: (1) It importantly stresses the cognitive or philosophic causes of emotional disturbance and of family disruption. (2) It teaches partners that they largely disturb themselves and that they can effectively refuse to continue to do so. (3) It almost always employs a number of cognitive, emotive, and behavioral techniques but employs them not merely to achieve symptomatic change but to help couples achieve a profound philosophic reconstruction that will, hopefully, lead to elegant and permanent change. It clearly acknowledges the biological as well as the sociological bases of disturbance, and therefore stresses vigorous and forceful, active-directive methods that will impinge upon and help alter the strongly held disturbances that partners frequently experience. (5) It holds to a rigorously scientific and yet highly humanistic outlook in both its theory and its practice. (6) It stresses a phenomenological, intraindividual, and depth-centered approach to understanding and tackling human disturbance, but at the same time uses practical problem-solving and skill-straining methods of changing family situations and interactions.     

Comments on sandra Warnock's “Rational-emotive therapy and the christian client”

Comments on Warnock's article which shows that the philosophy and actions of Jesus demonstrate that he held some of the basic ideas of rational-emotive therapy and that pointing this out to Christian clients may be of help to them.     

A dictionary of rational-emotive feelings and behaviors

Rational-emotive therapy (RET) hypothesizes that people mainly make themselves emotionally disturbed and dysfunctional in their behavior by starting with rational Beliefs (rBs) about their Goals (G) and then by consciously or unconsciously converting these into irrational Beliefs (iBs) or dogmatic, absolutistic musts and commands. To help clients and others to clearly see the differences between their rational Beliefs and their irrational Beliefs, to understand the disordered feelings and behaviors to which the latter lead, and to help them become more rational, less disturbed, and less dysfunctional in their activities, the authors have constructed and herewith present a dictionary of rational-emotive equivalents.Ted Crawford is a Consultant on Communication and Group Processes in Santa Barbara, California.

Effects of self-generated rules on the development of schedule-controlled behavior.

College students responded under a multiple differential-reinforcement-of-low-rate 5-s fixed-ratio 8 schedule, with components alternating every 2 min. After 40 programmed minutes of acquisition and 12 min of maintenance, without notice, both schedules changed to extinction for 28 min. During acquisition, between alternations of the multiple schedule, some subjects were asked to develop rules describing the schedule contingencies. Other subjects were given these same rules between alternations, and a third group neither received nor were asked to develop rules. By the end of the acquisition phase, self-generated-rule subjects were more likely to show schedule-typical behavior than were subjects not asked to generate rules. The behavior of those given rules was similar to those asked to generate rules at the end of acquisition, but yoked-rule subjects acquired schedule-typical behavior at a quicker rate. By the end of extinction, during the period corresponding to the previous fixed-ratio interval, all no-rule subjects who had earned points during acquisition and maintenance were responding at a rate of less than 30 responses per minute. Only 3 of the 9 self-generated-rule subjects and 2 of the 5 yoked-rule subjects were similarly responding at this low rate. Results suggest that asking subjects to develop self-rules facilitates acquisition, but can retard extinction. Results also suggest that self-generated rules function similarly to external rules.     

Selecting Information on Job Content or Job Context: The Moderating Effect of One's Own Epistemic Authority

The study investigated the effect of self-ascribed epistemic authority (SAEA) on proclivity to choose information either about job content or about job context. Subjects expressed their attitudes toward a job offer on the basis of information either about job content alone or about job content and job context. It was found that in the process of evaluating a job offer, people with different levels of SAEA tended to focus on different kinds of information-job-content or job-context characteristics. The higher the SAEA, the greater was the effect of job-content characteristics on their evaluation of the job offer. By contrast, when the job-content characteristics were supplemented with attractive job-context characteristics, the relationship between SAEA and job-offer evaluation was low and insignificant. Subjects low on SAEA had relatively low preference for using job-content characteristics as criteria for job-offer evaluation.
