Primacy effects induced by temporal or physical context shifts are attenuated by a preshift test trial

When subjects are sequentially trained with a cue (A) paired separately with two outcomes (B and C) in different phases (i.e., A-B pairings followed by A-C pairings) testing in the training context after short retention intervals often reveals recency effects (i.e., stronger influence by A-C). In contrast, testing after long retention intervals or testing in a context different from that of training sometimes reveals primacy effects (A-B). Three experiments were conducted using rats in a Pavlovian conditioned bar-press suppression preparation to ascertain whether a nonreinforced test trial in the training context soon after training can attenuate this shift to primacy. Experiment 1 demonstrated that exposure to A shortly after both phases of training, but prior to a long retention interval, can attenuate shifts from recency to primacy otherwise observed with a long retention interval. Experiment 2 showed that exposure to A in the training context can also eliminate the shift from recency to primacy otherwise produced by shifting the physical context between training and test. Experiment 3 discredited a potential account of the results of Experiments 1 and 2. The effects observed in Experiment 1 and 2 are interpreted as early testing in the training context serving to initiate rehearsal of the A-C association due to the temporal proximity of A-C training.     

Exploring Mothers’ and Fathers’ Relationships with Sons Versus Daughters: Links to Adolescent Adjustment in Mexican Immigrant Families

Drawing on ecological and gender socialization perspectives, this study examined mothers’ and fathers’ relationships with young adolescents, exploring differences between mothers and fathers, for sons versus daughters, and as a function of parents’ division of paid labor. Mexican immigrant families (N?=?162) participated in home interviews and seven nightly phone calls. Findings revealed that mothers reported higher levels of acceptance toward adolescents and greater knowledge of adolescents’ daily activities than did fathers, and mothers spent more time with daughters than with sons. Linkages between parent-adolescent relationship qualities and youth adjustment were moderated by adolescent gender and parents’ division of paid labor. Findings revealed, for example, stronger associations between parent–adolescent relationship qualities and youth adjustment for girls than for boys.     

Relationships Between Politics, Supervisor Communication, and Job Outcomes

Perceptions of organizational politics (POPs) are ever present and have been shown to have many negative effects. This study investigated the influence of perceptions of politics on the consequences of turnover intentions and job frustration; 2 important outcomes in the organizational politics literature. Additionally, this study examined the role of supervisor communication as a moderator of these relationships. We investigated the relationships in a sample of 246 alumni from a midwestern university who were working in a wide range of occupations. Our results provide support for positive associations between POPs and intentions to turnover and job frustration; supervisor communication moderated these relationships. Managerial recommendations and suggestions for future research are offered.     

Does attitude certainty beget self-certainty?

This research explores the possibility that changes in attitude certainty can affect general self-certainty and, thus, have consequences that extend beyond the attitude domain. Across two studies, attitude certainty is manipulated using repeated attitude expression and attitude consensus paradigms. The implications of these manipulations are tested for feelings of general self-uncertainty (Study 1) and global self-doubt about one’s abilities (Study 2). In each study, it is demonstrated that participants feel greater self-certainty under conditions of high rather than low attitude certainty, but only when they view aspects of the attitude as central to their self-concept.     

Do counselling supervisors want or need to have their supervision supervised? An exploratory study

In response to a survey of counselling supervisors, 70 practitioners provided information about their practice as supervisors of counsellors and supervisors of supervisors. Questions were asked about the practice of supervision for supervision and attitudes towards the BAC Code of Ethics and Practice for Supervisors requirement that supervisors have access to supervision for their supervisory work. All but six of the respondents claimed to have supervision for supervision. In response to questions about the helpfulness, general importance, ethical importance and desirability of supervision for supervision, for which a bipolar visual analogue scale was provided, mean scores were all above 70%, indicating that there was considerable satisfaction with supervision for supervision requirements. Factor analysis revealed only one factor including all four questions. Questions were asked about contracts with supervision supervisors. A total of 55.7% used the same supervisor for their clinical work and supervision. In response to a question about issues raised in supervision, four categories accounted for the majority of comments: boundaries, competence of supervisees, training and ethics.     

Sex differences during visual scanning of occlusion events in infants

A growing number of sex differences in infancy have been reported. One task on which they have been observed reliably is the event-mapping task. In event mapping, infants view an occlusion event involving 1 or 2 objects, the occluder is removed, and then infants see 1 object. Typically, boys are more likely than girls to detect an inconsistency between a 2-object occlusion event and a 1-object display. The current research investigated underlying reasons for this sex difference. Three eye-tracking experiments were conducted with infants at 9 and 4 months (mean age). Infants saw a ball-box or ball-ball occlusion event followed by a 1-ball display; visual scanning of the occlusion event and the 1-ball display was recorded. Older boys were more likely than older girls to visually track the objects through occlusion and more likely to detect an inconsistency between the ball-box event and the 1-ball display. In addition, tracking objects through occlusion was related to infants' scanning of the 1-ball display. Both younger boys and girls failed to track the objects through occlusion and to detect an inconsistency between the ball-box event and the 1-ball display. These results suggest that infants' capacity to track objects through occlusion facilitates extraction of the structure of the initial event (i.e., the number of distinct objects involved) that infants can map onto the final display and that sex differences in the capacity emerge between 4 and 9 months. Possible explanations for how the structure of an occlusion event is extracted and mapped are considered.     

Self-recognition and the right prefrontal cortex

Although the anatomical and functional substrates subserving face recognition have been subject to extensive investigation, the underpinnings of self-face recognition are not well understood. Given the evidence that own-face recognition has been demonstrated by a select number of species, it is intriguing to speculate whether self-face recognition is accomplished via a 'self-network' or simply a 'face-network' within the brain. Furthermore, the relationship of self-recognition to other self-processes, such as self-evaluation and autobiographical retrieval, are not clearly defined. However, data from fMRI, ERPs and repetitive transcranial magnetic stimulation as well as from split-brain studies and patients with focal lesions, indicate that the prefrontal cortex, with possible right hemisphere lateralization, may be a preferential component in self-recognition. Studies using these methods, as well as PET, have indicated that the self-processes of self-evaluation and autobiographical memory preferentially engage networks within the right fronto-temporal region. Although it is highly improbable that there is a 'self-recognition' or 'self' center, it appears that there may be a bias for the processing of 'self' within the right prefrontal cortex.
