Repetition effect with picture stimuli: Possible implications for clarity

Increasing recognition accuracy with repeated presentations was demonstrated for complex pictorial stimuli (real-world photographs) by accuracy, signal detection, and confidence of decision indicators. Consistent with other research, the effect occurred only for short stimulus durations. The effect occurred for both old and new pictures, the rate of improvement being greater for old than for new pictures. Experiment II utilized focus-degraded stimuli to demonstrate that amount of information artifacts were not responsible for the observed differences between responses to old and new pictures.     

Effect of the length of the runs of repetitions on the simple RT-ISI relationship

In a simple RT task the temporal organization of the preparatory processes during a given trial depends upon the time characteristics of the total experimental situation as well as upon the information gathered during one or more previous trials. The present experiment was run in order to determine whether or not these long and short term effects operate independently or interact. The effects of the preceding ISI durations on the simple RT for an ISI 1 (1.5 s) or an ISI 2 (3.0 s) are analysed in 3 experimental conditions differing in the maximum number of successive repetitions (2, 3 or 7) of trials with the same ISI. The results show that the distribution of the preparatory activity during a given trial depends firstly on the number of successive ISIs of the same duration preceding this trial, and secondly on the maximum number of repetitions. An explanation of the subjects' strategy based upon “cost of preparation” is proposed.     

Nurturing and mythus bearing in clergy work motivation

The nature of Protestant clergy work motivation has been unclear. Attempts at clarification by clinical, sociological, and theological investigators have not been generally accepted. This study hypothesized that positive clergy motivation is based upon a preference for anurturing orientation to life and upon satisfaction achieved inmythus-bearing work tasks. One hundred and five parish ministers of a United Church of Christ Conference in the Middle Atlantic states were given the Myers-Briggs Type Indicator and the Work Task Rating Sheet. Responses were evaluated according to preferences for feeling and thinking orientations and according to satisfaction levels in the performance of work tasks. Although three of four specific hypotheses were not supported by statistically significant results, enough support was found fornurturing preference and satisfaction inmythus bearing to warrant further study of these concepts.     

Phonological and semantic priming: Evidence for task-independent effects

The questions asked in the present experiments concern the generality of semantic and phonological priming effects: Do these effects arise automatically regardless of target task, or are these effects restricted to target tasks that specifically require the retrieval of the primed information? In Experiment 1, subjects produced faster color matching times on targets preceded by a masked rhyming prime than on targets preceded by an orthographic control or an unrelated prime. This result suggests that automatic priming effects on the basis of phonological similarity can be obtained even when the target task does not make use of phonological information. This claim was reinforced in Experiment 2 in which a rhyme priming effect and a semantic priming effect were found in a semantic categorization task. In Experiment 3, the target task was phonological (rhyme detection), and, again, both phonological and semantic priming effects were observed. Finally, in Experiments 4 and 5, in a replication and an extension of Experiment 1, phonological and semantic priming effects were found in a color matching task, a task involving neither phonological nor semantic processing. These results are most straightforwardly interpreted by assuming that both semantic and phonological priming effects are, at least in part, due to automatic activation of memorial representations.     

Prejudice Toward Immigrants1

In the present study, 4 variables (realistic threats, symbolic threats, intergroup anxiety, and negative stereotypes) were used to predict prejudice toward immigrants from Cuba, Mexico, and Asia in samples of students from states in the United States that are affected by immigration from these areas (Florida, New Mexico, and Hawaii, respectively). All 4 variables were significant (or marginally significant) predictors of attitudes toward these immigrant groups. Evidence is presented that the predictor variables are conceptually and empirically distinct. However, these variables do appear to be tied together by an underlying theme: They all concern threats to the in-group or its members. Some of the implications of the results for intergroup relations are discussed.     

Supervisees' perspectives on the contribution of supervision to psychotherapy outcomes

Objective

The aim of this study was to examine supervisees' perspectives about the contribution of two predefined aspects of supervision, supervisory bond (SB) and didactic input of supervisor (DI), to their ascribed outcome of therapy.

Method

Supervisees anonymously assessed the SB, supervisors' DI and their contribution to therapy outcome. Assessment was quantitative and qualitative. The supervisory aspects were assessed using a questionnaire constructed for this study. Perceived contribution was evaluated by two scaled questions, and themes generated by an open question. Supervisees (n = 111) evaluated 16 supervisors and supervision’s contribution to psychotherapy outcomes of 111 clients.

Findings

Hierarchical regression showed that supervisees' age, supervisors' status and frequency of supervision accounted for 24% of the variance ascribed to outcome. SB and DI accounted for 51% of the variance. These values, which are higher than reported in the literature, may be attributed to the assessment of predefined aspects of supervision by the same assessor. Thematic analysis of the didactic input produced more themes than for the supervisory bond.

Conclusion

Sociodemographic variables and supervisory relationship variables determine supervisees' evaluations of supervision’s contribution to outcome.

Implications for practice

Training and supervision may benefit from information obtained from quantitative and qualitative measures regarding these and other predefined variables related to supervision. The in-depth look at views and experiences shared by supervisees may advance training, practice and research.     

Talking to a (Segregation) Wall: Intergroup Contact and Attitudes Toward Normalization Among Palestinians From the Occupied Territories

This article examines how Palestinians' intergroup contact experiences relate to their attitudes towards interactions with Israelis (i.e., normalization). We draw on four recent advances in intergroup contact literature. First, recent research indicates that positive contact can impede disadvantaged groups' motivation to challenge inequalities. Second, increased endorsement of normalization mediates this sedative effect of positive contact on motivation to resist in the West Bank. Third, negative contact has been related to increased motivation for social change. Fourth, institutions and societal norms shape the meaning of intergroup contact and its effect on intergroup relations. We hypothesize that negative experiences at checkpoints can act as reminders of institutionalized inequalities and thus attenuate sedative effects. Furthermore, we explore the contextual boundary conditions of such reminder effects. Analyses of cross-sectional survey conducted among a representative sample (N = 1,000) in the West Bank including Jerusalem showed that (1) positive intergroup contact related to normalization endorsement (sedative effect), (2) negative intergroup contact related to decreased normalization endorsement (mobilizing effect), and (3) negative contact experiences (at checkpoints) canceled out the effect of positive contact (reminder effect), but only in Jerusalem. Results suggest that the impacts of intergroup contact need to be interpreted in light of institutionalized forms of group inequality and segregation.     

Presurgery distress and specific response expectancies predict postsurgery outcomes in surgery patients confronting breast cancer.

Prior to scheduled surgery, patients frequently experience particularly high levels of distress and expect a variety of postsurgery symptoms. Surgery patients who confront breast cancer are no exception. It has been suggested that such presurgery distress and response expectancies are predictive of postsurgery outcomes. To test the contribution of presurgery distress and expectancies to common postsurgery symptom outcomes (pain, nausea, fatigue, and discomfort), 63 female patients undergoing breast cancer surgery were recruited to a prospective study. Results indicated that presurgery distress uniquely contributed to patients' postsurgery nausea, fatigue, and discomfort; specific expectancies uniquely contributed to pain intensity, pain unpleasantness, and fatigue (ps < .05). Consistent with expectancy theory, associations between response expectancies and postsurgery outcomes were not due to presurgery distress.     

Effect of tuned parameters on an LSA multiple choice questions answering model

This article presents the current state of a work in progress, whose objective is to better understand the effects of factors that significantly influence the performance of latent semantic analysis (LSA). A difficult task, which consisted of answering (French) biology multiple choice questions, was used to test the semantic properties of the truncated singular space and to study the relative influence of the main parameters. A dedicated software was designed to fine-tune the LSA semantic space for the multiple choice questions task. With optimal parameters, the performances of our simple model were quite surprisingly equal or superior to those of seventh- and eighthgrade students. This indicates that semantic spaces were quite good despite their low dimensions and the small sizes of the training data sets. In addition, we present an original entropy global weighting of the answers’ terms for each of the multiple choice questions, which was necessary to achieve the model’s success.
