Multiple views of spatial memory

Recent evidence indicates that mental representations of large (i.e., navigable) spaces are viewpoint dependent when observers are restricted to a single view. The purpose of the present study was to determine whether two views of a space would produce a single viewpoint-independent representation or two viewpoint-dependent representations. Participants learned the locations of objects in a room from two viewpoints and then made judgments of relative direction from imagined headings either aligned or misaligned with the studied views. The results indicated that mental representations of large spaces were viewpoint dependent, and that two views of a spatial layout appeared to produce two viewpoint-dependent representations in memory. Imagined headings aligned with the study views were more accessible than were novel headings in terms of both speed and accuracy of pointing judgments.     

Dimensions of perfectionism and goal commitment: A further comparison of two perfectionism measures

Research on perfectionism has suggested that a strong association exists between the setting and striving for excessively high standards. However, the motivational aspects of perfectionism have yet to be empirically identified. The purpose of the present study was to evaluate the usefulness and psychometric properties of a new goal commitment scale by assessing commitment to perfection in seven content areas. In addition to identifying individual differences in perfectionism goal commitment, the current research also investigated the association between commitment to perfectionism and trait indices of perfectionism. A sample of 261 students rated degree of commitment to perfectionistic goals and completed two multidimensional perfectionism scales that assess the personal and social aspects of perfectionism. Analyses confirmed the presence of individual differences in perfectionism goal commitment. Correlational tests revealed that the trait perfectionism dimensions were correlated with the goal commitment measure, but the findings varied as a function of the specific perfectionism goal. Overall, the current data are consistent with the view that the perfectionism construct has a salient motivational component. Our findings suggest that the assessment of goal commitment is a useful means of examining specific facets of the perfectionism construct.     

The concurrent validity of child Rorschach interpretations

Rorschach records were obtained by 10 examiners from 59 preschool children. These records were reliably scored and interpreted. Interpretation consisted of preparing a list of Rorschach concepts for each child. An additional number of Rorschach concepts of equal frequency in this sample were added to each child's list of concepts. Half of the concepts on each child's list were checked for agreement by school personnel. The children were described with consistency across judges and over time by the same judges. The school personnel were able to differentiate concepts that described each child from nonrelevant concepts. The Rorschach concepts provided data that was validated by teacher perception of these children. This methodology for Rorschach validation makes use of interpretive concepts derived directly from data rather than from reports.     

Ruminations on teaching projective assessment: an ideology, specific usages, teaching practices

Summary: This paper was written in reaction to current dissatisfaction with projective techniques. A credo for use of projective techniques emphasizes accountability, phenomeno-logical equality, and an eventual "giving-away" of assessment procedures through education. The primary legitimate usage is nonpsychometric; an interview focused on growth in various contexts. Secondary usages include examples of procedural or methodological effects to provide specific information. Training practices germane to the credo and legitimate usages are presented.     

Perceived control and health

Perceived control (PC) is defined as thebelief that one can determine one’s own internal states and behavior, influence one’s environment, and/or bring about desired outcomes. Two important dimensions of PC are delineated: (1) whether the object of control is located in the past or the future and (2) whether the object of control is over outcome, behavior, or process. A variety of constructs and measures of PC (e.g., efficacy, attribution, and locus of control) are discussed in relation to these dimensions and selected studies are reviewed. The issues, controversies, and limits of the research on perceived control and health are addressed in terms of the antecedents and consequences of perceived control. Investigations should clearly conceptualize the object of perceived control, use measures that match the conceptualization, and when attempting to manipulate control, directly measure perceived control. The relation between PC and health outcomes is complex, and different aspects of PC may interact to affect health outcomes.     

The effects of episodic and semantic memory on the identification of sentences masked by white noise

Two studies examine how episodic and semantic memory affect subjects’ abilities to repeat sentences masked by white noise. Subjects first hear a list of 70 sentences that are not masked. Subjects in the framework conditions are told prior to hearing the list that all sentences refer to a contextual framework concerning a deserted island. Subjects in the no-framework groups are not given this information. Subjects in the framework-after condition are given this information only after hearing the list of sentences. Subjects then perform a white-noise identification task. The results indicate that framework subjects are able to identify both old and new framework-related information better than other subjects. Subjects in the no-framework and framework-after conditions identify old information better than control subjects who do not participate in an acquisition phase. Emphasis is placed on the interdependence of episodic and semantic memory, including conditions leading to such interdependence.     

The influence of vision on the absolute identification of sound-source position

The influence of vision on auditory localization was assessed in an absolute identification paradigm using sighted and blindfolded subjects. Vision improved the accuracy of judgments directly in front of, to the side of, and behind the head of subjects in the horizontal plane, but had little relevance to vertical-plane localization. The exact form of the observed facilitation depended on the orientation of the speaker array to the head. In a second experiment involving sound localization in 10 visual environments, there was evidence for the operation of two distinct influences of vision on directional hearing. One result supported the hypothesis that vision provides a frame of reference for judgments, and a second indicated the importance of vision to the maintenance of spatial memory.     

Toward a dialectical metatheory for psychotherapy

This paper develops a metatheoretical perspective for psychotherapy using a dialectical approach. A brief review of current theoretical writings shows how little attention is paid to the person and family in social context. Dialectics is then examined from an historical perspective to illustrate how it can enrich current theoretical work in psychotherapy. In concluding, the paper describes the ways in which a dialectical metatheory could delineate more precisely the relationship between the person and the society in which we live.
