The reliability of three visual perception tests used to assess adults

Summary.-The reliability of three adult visual perceptual tests was investigated. Participants aged 20 years and older (N = 221; 49 adults with neurological impairment, 172 adults without) completed the Developmental Test of Visual Perception-Adolescent and Adult (DTVP-A), the Motor-Free Visual Perception Test-3 (MVPT-3), and the Test of Visual Perceptual Skills (non-motor) Third Edition (TVPS-3). Participants (n = 46) without neurological impairment completed these tests twice. Cronbach's alpha for the DTVP-A, MVPT-3, and TVPS-3 total scales were .86, .74, and .80 and test-retest correlations .51, .71, and .72, respectively.     

Repeatable battery for the assessment of neuropsychological status (RBANS) may be valid in men ages 18 to 201

The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) provides standardized scores for adults ages 20 to 89 years. However, there are situations in which the use of the RBANS for adults ages 18 to 20 years may be appropriate and have practical advantages. Thus, at present, an examiner who uses the RBANS for adult patients must rely on an entirely different evaluation tool for those adult patients under the age of 20 years. This preliminary investigation suggests the RBANS is a valid measure for men ages 18 to 20 years.     

Social influences on the emotion process

Philosophical and psychological theory has traditionally focused on intra-individual processes that are entailed in emotions. Recently sociologists, cultural anthropologists, and also social psychologists have drawn attention to the interpersonal nature of emotions. In this chapter we focus on the influence of others on emotional experiences and expressions. We summarise research on social context effects which shows that both emotional expression and experience are affected by the presence and expressiveness of other people. These effects are most straightforward for positive emotions, which are enhanced in the company of others. In the case of negative emotions, the effects of social context depend on the circumstances in which the emotion is elicited, and on the role of other persons in this situation. We discuss these social context effects in the light of a more general theoretical framework of social appraisal processes.

Beyond smile dynamics: mimicry and beliefs in judgments of smiles

The judgment that a smile is based on "true," usually positive, feelings affects social interaction. However, the processes underlying the interpretation of a smile as being more or less genuine are not well understood. The aim of the present research was to test predictions of the Simulation of Smiles Model (SIMS) proposed by Niedenthal, Mermillod, Maringer, and Hess (2010). In addition to the perceptual features that can guide the judgment of a smile as genuine, the model identifies the conditions that the judgments rely on: (a) the embodiment of the facial expression and its corresponding state, and (b) beliefs about the situations in which genuine smiles are most often expressed. Results of two studies are consistent with the model in that they confirm the hypotheses that facial mimicry provides feedback that is used to judge the meaning of a smile, and that beliefs about the situations in which a smile occurs guides such judgments when mimicry is inhibited.
