Apraxia differs in corticobasal degeneration and left-parietal stroke: A case study.

Corticobasal degeneration (CBD) is a progressive disorder characterized by both cortical and basal ganglia dysfunction such as asymmetrical apraxia, and akinetic rigidity, involuntary movements, and cortical sensory loss. Although apraxia is a key finding for the differential diagnosis of CBD, it has not been determined whether the features of apraxia seen in subjects with CBD are similar to those features exhibited by subjects with left-hemisphere damage from stroke. Therefore, for both clinical purposes and in order to better understand the brain mechanisms that lead to apraxia in CBD, we studied praxis in a patient with CBD and compared him to patients who are apraxic from left-parietal strokes. We used three-dimensional movement analyses to compare the features of apraxic movement. This subject with CBD was a dentist whose initial complaint had been that he "forgot" how to use his tools in the mouths of his patients. Analyses were performed on the trajectories made when using a knife to actually slice bread, and when repetitively gesturing slicing made to verbal command. Movements of the left hand, wrist, elbow, and shoulder were digitized in 3-D space. Although the CBD subject was clearly apraxic, the features of his apraxia differed markedly from those of the subjects with lesions in the left parietal lobe. For movements to command, the CBD subject showed joint coordination deficits, but his wrist trajectories were produced in the appropriate spatial plane, were correctly restricted to a single plane, and, like control subjects, were linear in path shape. However, when he was actually manipulating the tool and object, all of these aspects of his trajectories became impaired. In contrast, the deficits of the apraxic subjects with left-parietal damage were most pronounced to verbal command with their movements improving slightly although remaining impaired during actual tool and object manipulation. Unlike patients with parietal strokes, patients with CBD have degeneration in several systems and perhaps deficits in these other areas may account for the differences in praxic behavior.     

Indigenization of Psychology: Empirical Assessment of Progress in Indian Research

The development of an indigenous psychology has generally been documented by examples of indigenous constructs and conceptual analyses of their emergence. In contrast, the present article proposes an empirical approach. Indigenization is conceived as a gradual process that may be operationalized, and measured by content analysis of journal articles as the discipline develops and changes. Measures are proposed to assess the extent to which the concepts, problems, hypotheses, methods, and tests: (a) emanate from, (b) adequately represent, and (c) reflect back upon, the cultural context in which behaviour is observed. Application of these to 355 empirical and 31 theoretical articles from Indian journals and 39 foreign empirical articles published by Indian psychologists, indicates some slight movement toward an indigenous discipline, and some interesting relationships that assist in understanding its development. Factors contributing to indigenization and the utility of the empirical approach are discussed.     

Slow and steady wins the race: Life history,mate value,and mate settling

Life history theory explains how individuals decide to invest their limited resources, which involves several trade-offs. Particularly relevant to the current work, individuals can choose to invest in current or delayed reproduction (a slow life history strategy), which implicates a trade-off between the quantity and the quality of one’s offspring. Choosing to delay reproduction allows for increased self-investment, and previous research has demonstrated that traits requiring self-investment are related to higher mate value. As such, the current study hypothesizes that slow life history strategy will predict high personal mate value and high levels of partner mate-value within heterosexual partnerships. Similarly, those with a slow life history strategy should display fewer tendencies toward mate-settling. The current work employs both subjective and objective measures of mate value within mateships to investigate these hypothesized relationships. As hypothesized, significant positive relationships among life history and mate value were detected, suggesting that a slower life history strategy corresponds to high ratings of mate value for both self and partner. Also, life history strategy is a significant predictor of subjective, objective, and Mate Value Inventory ratings of partner and self. Further implications and potential future works are discussed.     

Trait Goal Orientation, Self-Regulation, and Performance: A Meta-Analysis

Purpose

The purpose of this paper is to meta-analytically examine trait goal orientation constructs and their relationships with the self-regulation variables of self-monitoring, self-evaluations, self-reactions, and self-efficacy as well as task performance across a range of contexts.

Design, Methodology, Approach

Data were gathered from published and unpublished research examining the goal orientation construct and self-regulation and/or task performance. Effect sizes from 102 research reports involving over 16,000 participants were included.

Findings

In general the mastery-approach goal orientation construct was positively related to the self-regulation and performance variables. Conversely, negative relationships were found between the performance-avoid goal orientation and those variables. Relationships between goal orientation and self-regulation tended to be higher compared to those found for goal orientation and performance. Overall, the findings support the discriminant validity of the three factors of goal orientation (mastery-approach, performance-approach, performance-avoid).

Practical Implications

Practitioners and researchers will benefit from learning that mastery-approach goal orientation consistently relates to self-regulation and task performance. The findings indicate that a mastery-approach goal orientation could serve as a meaningful predictor in selection processes or as an explanatory variable of motivation.

Originality/Value

The present study updates and expands upon past research by focusing on relationships of trait goal orientation across a variety of contexts. The results extend meta-analytic results to a wider range of self-regulatory variables.     

Psychology through international congresses: differences between regions, countries, and congresses

A published database of presentations from the seven most recent International Congresses of Applied Psychology (ICAPs) was compared to a similar but unpublished database (Adair, Anguas-Plata, Unik, & Radons, 2009) on the International Congresses of Psychology (ICPs) for the years 1996-2004. Analyses revealed phenomena characteristic of attendance at both international congresses: Participation rates spike dramatically for host countries; less dramatic regional surges in participation occur when the congress is held in a neighbouring country. Psychologists from 117 different countries participated in the seven recent congresses (ICAP and ICP) from 1994 to 2006. Overall ICP was double the size of ICAP, and represented a larger set of countries at each of its congresses. Regardless of location, most participants at both congresses came from the same 11 economically advantaged and seven majority-world countries. Congress presentations are dispersed across a much larger number of countries than are journal publications. The USA, for example, had modest 14.4% (ICAP) and 11.6% (ICP) presentation rates, much smaller than its majority share of publications (Adair, 2009 ). By contrast, the USA had the greater share of invited addresses at both ICAP (33.7%) and ICP (28.9%) congresses. Nonetheless, the majority-world countries contributing to both ICAP and ICP are clearly indicative of where the discipline is gaining strength and importance to international psychology. The emergence of Iran as a new leading national contributor to the two most recent international congresses, and the rise in the proportion of presentations by majority-world psychologists at ICAPs from only about one in five to more than one of every three presentations in recent congresses are findings consistent with Zakaria's (2008) analysis of changes taking place in the world. Within international congresses, certainly, the "rise of the rest" is changing the face of international psychology.     

Advanced Research and Training Seminars (ARTS) Report on ARTS 2002

This article reports on the Advanced Research and Training Seminars (ARTS) program that was held in Singapore during July, 2002. The seminars were sponsored jointly by the three international psychology associations—the International Union of Psychological Science (IUPsyS), the International Association of Applied Psychology (IAAP), and the International Association for Cross‐Cultural Psychology (IACCP). ARTS is an educational program for psychologists from low‐income (developing and in‐transition) countries. The seminars are held in proximity of the international congresses each even‐numbered year to enable participants to attend one or more congresses in addition to receiving specialized instruction. Also, it is expected that the educational benefits to participants will extend to their students and colleagues with whom they interact on return to their home countries.

Optimum split-half reliabilities for the Rorschach: projective techniques are more reliable than we think

A new technique for optimizing split-half reliability estimates yielded substantial and comparable increases in indexes of internal reliability for some major Rorschach variables across two diverse samples. Practical suggestions for applying this method to other projective tests were advanced. The inadvisability of computing odd-even reliability coefficients without regard to split-half distributional anomalies is addressed.     

Cultural Dimensions,Gender, and the Nature of Self-concept: A Fourteen-country Study

Ratings of the importance of and satisfaction with 20 areas of the self were obtained from 3604 first or second year social science undergraduates from 14 countries (15 cultures). Factor analysis at the culture by gender level supported four factors for both sets of ratings. The resulting factor scores were analyzed for mean differences according to the cultural dimension of Individualism-Collectivism by Gender and by correlations with other cultural dimenions and economic indicators. It was found that participants from the 10 collectivist cultures placed greater salience for their self-concepts on “family values” than did those from the individualist cultures. However, this cultural difference was not found for “social relationships”. The expected gender differences, with females valuing “family values” and “social relationships” more highly, were found only for the individualist countries. The findings indicate that there may be a strong cultural level interaction effect between gender and Individualism-Collectivism on the nature of self-conceptions, and that the “family” and “social” aspects of self-concept in collectivist countries need to be considered separately.
