Knowing color terms enhances recognition: further evidence from English and Himba

Two experiments attempted to reconcile discrepant recent findings relating to children’s color naming and categorization. In a replication of Franklin and colleagues (Journal of Experimental Child Psychology, 90 (2005) 114-141), Experiment 1 tested English toddlers’ naming and memory for blue-green and blue-purple colors. It also found advantages for between-category presentations that could be interpreted as support for universal color categories. However, a different definition of knowing color terms led to quite different conclusions in line with the Whorfian view of Roberson and colleagues (Journal of Experimental Psychology: General, 133 (2004) 554-571). Categorical perception in recognition memory was now found only for children with a fuller understanding of the relevant terms. It was concluded that color naming can both underestimate and overestimate toddlers’ knowledge of color terms. Experiment 2 replicated the between-category recognition superiority found in Himba children by Franklin and colleagues for the blue-purple range. But Himba children, whose language does not have separate terms for green and blue, did not show a cross-category advantage for that set; rather, they behaved like English children who did not know their color terms.     

Relational Autonomy and Paternalistic Interventions

Relational conceptions of autonomy attempt to take into account the social aspects of autonomous agency. Those views that incorporate not merely causally, but constitutively necessary relational conditions, incorporate a condition that has the form:

(RelAgency) A necessary condition for autonomous agency is that the agent stands in social relations S.

I argue that any account that incorporates such a condition (irrespective of how the relations, S, are spelt out) cannot play one of autonomy’s key normative roles: identifying those agents who ought to be protected from (hard) paternalistic intervention. I argue, against objections from Oshana, that there are good reasons for maintaining the notion of autonomy in this role, and thus that such relational conceptions should not be accepted. This rejection goes beyond that from John Christman, which holds only for those relational conditions which are value-laden.     

A Communicative Conception of Moral Appraisal

I argue that our acts of moral appraisal should be communicative. Praise and blame should communicate, to the appraised, information about their status and competences as moral agents; that they are recognised by the appraiser as a competent moral agent, and thus a legitimate candidate for appraisal. I argue for this thesis by drawing on empirical data about factors that can affect motivation. On the basis of such data, I formulate a constraint, and argue that two prominent models of moral appraisal – a consequentialist model and Wallace’s ‘evaluative response’ model – violate this constraint. The model that I propose – the communicative conception of appraisal – does not violate this constraint. This conception, I argue, can provide a fuller picture of the role of appraisals in deepening agents’ commitment to moral norms. On this model, praise and blame has not only an evaluative component, but also communicates to the agent competence affirming information.

The Prediction of Family Interaction from a Battery of Projective Techniques

This study first explored the adequacy of items on the Rorschach Rating Scale (RRS), which measures Rorschach constructs from a variety of scoring systems. Analyses determined that all items had an adequate capacity to differentiate people and none were clearly redundant. At the same time, the current version of the RRS requires good reading comprehension skills for accurate completion (13th grade level). Next, we developed two sets of RRS scales. Factor analysis of observer ratings (N = 234) indicated the RRS contained six broad, empirically derived factors. In addition, 19 conceptually derived scales were developed from the RRS item pool. Both sets of scales were evaluated for reliability and then compared to the Big Five model (B5M) of personality through a series of factor and regression analyses. Results indicated that RRS scales do not provide adequate definition of all B5M dimensions and B5M scales do not provide adequate definition of all RRS dimensions. We discuss the place of psychotic processes within a comprehensive model of personality and other implications from these findings.     

A standard for test reliability in group research

Many authors adhere to the rule that test reliabilities should be at least .70 or .80 in group research. This article introduces a new standard according to which reliabilities can be evaluated. This standard is based on the costs or time of the experiment and of administering the test. For example, if test administration costs are 7 % of the total experimental costs, the efficient value of the reliability is .93. If the actual reliability of a test is equal to this efficient reliability, the test size maximizes the statistical power of the experiment, given the costs. As a standard in experimental research, it is proposed that the reliability of the dependent variable be close to the efficient reliability. Adhering to this standard will enhance the statistical power and reduce the costs of experiments.     

Exposure to an urban environment alters the local bias of a remote culture

There is substantial evidence that populations in the Western world exhibit a local bias compared to East Asian populations that is widely ascribed to a difference between individualistic and collectivist societies. However, we report that traditional Himba - a remote interdependent society - exhibit a strong local bias compared to both Japanese and British participants in the Ebbinghaus illusion and in a similarity-matching task with hierarchical figures. Critically, we measured the effect of exposure to an urban environment on local bias in the Himba. Even a brief exposure to an urban environment caused a shift in processing style: the local bias was reduced in traditional Himba who had visited a local town and even more reduced in urbanised Himba who had moved to that town on a permanent basis. We therefore propose that exposure to an urban environment contributes to the global bias found in Western and Japanese populations.     

Practice schedule and cognitive style interaction in learning a maze task

In the present study the effects of contextual interference on the retention and transfer performance of reflectives and impulsives on a maze task were studied. Forty-seven subjects were randomly assigned to either a high contextual interference group or to a low contextual interference group. Within the two groups subjects were further classified according to their preferred modes of responding. Retention and transfer were measured immediately following practice and after a 4-week delay. The dependent variables were tracing time and errors. Reflectives made fewer errors and moved more quickly after practising under conditions of high contextual interference. Impulsives tended to have fewer errors after practising under conditions of high contextual interference but moved more slowly. Based on these results it was suggested that trainers consider individual differences in reflectivity-impulsivity before designing particular practice schedules.
