Building a research base for community services for children and families: What we know and what we need to learn

We examine the knowledge base for community-based mental health services for youth and their families. A brief historical perspective on the development of community services is presented, and the fundamental components of a comprehensive child mental health service system are described. Outcome studies for service components as well as the service system as a whole are summarized. Research related to the context of treatment, i.e., service setting, cost, is presented. The authors conclude that a research base for child and family services is emerging, but there is still a paucity of well designed studies that address the complexities of a community-based system as well as the critical outcome questions that need to be addressed. Finally, promising service system developments are described and recommendations for future research are presented.     

Indirect majority and minority influence: An exploratory study

In a 2 × 2 design, 85 subjects were asked to estimate the size of angles (direct influence) that were either 90 or 85°, after being confronted with incorrect judgements of a majority (88 per cent) or a minority (12 per cent) of people estimating the angles at 50°. Additionally, pre- and post-test measures were used to establish indirect influence on subjects' judgements pertaining to acute angles (i.e. on the estimation of the length of lines constituting the angles, and on the imaginary weight of figures represented by these angles). Overall, little direct influence is observed. This may partly be due to the introduction of a denial of the credibility of the source in all conditions. In fact, some evidence of direct influence is only found in the majority–85° angles condition. An instance of indirect influence (on the estimation of length of lines) appeared as the result of a majority stance when the angles in the experimental phase were 90°. When these angles were 85°, indirect minority influence (on the estimation of weight of figures) was observed. These effects had been predicted on the basis of the hypothesis stating that indirect majority influence would be possible when subjects expected consensus on the correct response (in the 90° angles condition), without being able to reach consensus at the manifest level (because of the denial and the restriction imposed by the clear shape of 90° angles). Indirect minority influence was hypothesized to be stronger in a situation that allows for diverse responses (i.e. for 85° angles).     

Majority and minority influence in inductive reasoning: A preliminary study

Ninety-three students were exposed to majority and minority influence in an inductive reasoning task. The former induced convergent thinking processes, though its effects were not reducible to mere compliance. The latter activated more divergent constructive processes, supporting the predictions of Conversion Theory.     

Aging, Memory, and Comprehension

There are changes in the ability to comprehend and remember information with aging. In general, older adults perform more poorly than younger adults at tasks that require knowledge of the information that was actually encountered. However, they can perform as well as or better than younger adults at tasks involving more global levels of understanding, such as in the use ofinformation in a situation model. This increased emphasis on situation models may serve to compensate for deficits at lower levels of processing and may be achieved through more focused selection of situation-defining information, increased dependence on schemas, and a broader generation and use of inferences.     

The stability of the factorial pattern of aircrew classification tests in four analyses

This study consists of four factor analyses of the Army Air Forces Aircrew Classification Batteries. The first was an analysis of the 1945 wartime battery, while the other three were analyses of the 1947 postwar battery, consisting of essentially the same variables, but using different samples. Eleven factors were found which had been identified and reported in previous analyses. An additional factor, possibly an artifact, was identified as an age-education doublet. The only factor which differed significantly in the analyses was pilot or flying interest. These factor analyses show that the factorial content of the tests remains quite similar in both wartime and postwar populations.The data reported in this study were collected as part of the United States Air Force Human Resources Research and Development Program and described in Research Bulletin 52-16. The opinions or conclusions contained in this report are those of the authors. They are not to be construed as reflecting the view or indorsement of the Department of the Air Force.     

Performance boosts in the classroom: Stereotype endorsement and prejudice moderate stereotype lift

The present study (N = 293) examined whether stereotype endorsement and prejudice moderate stereotype lift (i.e., a performance boost caused by the salience of a negative out-group stereotype in the testing situation). The stereotype in the focus of inquiry was the belief that immigrant students have lower intellectual ability than native students. French native high school students performed an intellectual test in a condition of low stereotype salience (the test was presented as assessing individual differences) or in a condition of high stereotype salience (the test was presented as assessing group differences between African immigrants and native students). As expected, results indicated that native students high in stereotype endorsement and those high in prejudice performed better in the high than in the low stereotype salience condition, whereas those low on these constructs did not. By identifying two moderators of stereotype lift, this study sheds new light on the achievement gap between immigrant and native students in educational institutions.     

Group motives in threatening contexts: When a loyalty conflict paradoxically reduces the influence of an anti‐discrimination ingroup norm

The influence of pro‐ versus anti‐discrimination ingroup norms on Swiss nationals' attitudes towards foreigners was investigated as a function of national identification and perceived material ingroup threat. As predicted, results revealed a significant interaction between identification and threat: High identifiers showed a more negative attitude than low identifiers mainly when perceived threat was high. In other words, high identifiers conformed to the pro‐discrimination norm, but showed a counter‐conformity effect for the anti‐discrimination norm. Additional results revealed that high identifiers actually disagreed with the anti‐discrimination norm when perceived threat was high, but that they were more attached to the ingroup. These findings suggest that when the ingroup norm is not an appropriate response to an ingroup threat (i.e. anti‐discrimination norm), high identifiers find themselves in a loyalty conflict: they are unable to simultaneously conform to the group norm and protect the group. This conflict was resolved through a compensatory mechanism: High identifiers distanced themselves from the ingroup norm in order to protect the group (i.e. by increasing negative attitudes towards foreigners) but reinforced other ingroup ties (i.e. by increasing attachment to the ingroup values).

More data trumps smarter algorithms: Comparing pointwise mutual information with latent semantic analysis

Computational models of lexical semantics, such as latent semantic analysis, can automatically generate semantic similarity measures between words from statistical redundancies in text. These measures are useful for experimental stimulus selection and for evaluating a model’s cognitive plausibility as a mechanism that people might use to organize meaning in memory. Although humans are exposed to enormous quantities of speech, practical constraints limit the amount of data that many current computational models can learn from. We follow up on previous work evaluating a simple metric of pointwise mutual information. Controlling for confounds in previous work, we demonstrate that this metric benefits from training on extremely large amounts of data and correlates more closely with human semantic similarity ratings than do publicly available implementations of several more complex models. We also present a simple tool for building simple and scalable models from large corpora quickly and efficiently.
