Sound naming in neurodegenerative disease

Modern cognitive neuroscientific theories and empirical evidence suggest that brain structures involved in movement may be related to action-related semantic knowledge. To test this hypothesis, we examined the naming of environmental sounds in patients with corticobasal degeneration (CBD) and progressive supranuclear palsy (PSP), two neurodegenerative diseases associated with cognitive and motor deficits. Subjects were presented with 56 environmental sounds: 28 sounds were of objects that required manipulation when producing the sound, and 28 sounds were of objects that required no manipulation. Subjects were asked to provide the name of the object that produced the sound and also complete a sound-picture matching condition. Subjects included 33 individuals from four groups: CBD/PSP, Alzheimer disease, frontotemporal dementia, and normal controls. We hypothesized that CBD/PSP patients would exhibit impaired naming performance compared with controls, but the impairment would be most apparent when naming sounds associated with actions. We also explored neural correlates of naming environmental sounds using voxel-based morphometry (VBM) of brain MRI. As expected, CBD/PSP patients scored lower on environmental sounds naming (p < 0.007) compared with the controls. In particular, the CBD/PSP patients scored the lowest when naming sounds of manipulable objects (p < 0.05), but did not show deficits in naming sounds of non-manipulable objects. VBM analysis across all groups showed that performance in naming sounds of manipulable objects correlated with atrophy in the left pre-motor region, extending from area six to the middle and superior frontal gyrus. These results indicate an association between impairment in the retrieval of action-related names and the motor system, and suggest that difficulty in naming manipulable sounds may be related to atrophy in the pre-motor cortex. Our results support the hypothesis that retrieval of action-related semantic knowledge involves motor regions in the brain.     

Trait Entitlement and Perceived Favorability of Human Resource Management Practices in the Prediction of Job Satisfaction

Purpose  

Inconsistency in offerings of human resource management (HRM) practices across organizations is potentially problematic for employees with high levels of entitlement as they tend to believe they get less than they deserve. The purpose of this study was to examine the moderating effect of trait entitlement on the relationship between the favorability of HRM practices and job satisfaction.     

Testing the choice model of social cognitive career theory across Holland themes: A meta-analytic path analysis

Social cognitive career theory (SCCT; Lent, Brown, & Hackett, 1994) seeks to explain the factors that shape educational and vocational interests and choices. We used meta-analytic path analyses to synthesize data (from 1981 to 2008) relevant to SCCT’s interest and choice hypotheses, organizing the literature according to Holland’s (1997) broad occupational themes. Sufficient data were available to test (a) a 6-variable version of the interest/choice model in the Realistic, Investigative, and Enterprising themes, and (b) a 4-variable version of the model in the Artistic, Social, and Conventional themes. Analyses of both model versions were generally consistent with theoretical expectations. However, tests of the 6-variable model indicated better support for representing the pathways from contextual variables to choice goals as being partially mediated by self-efficacy and outcome expectations rather than as producing only direct linkages to goals. We consider implications of the findings for theory, research, and SCCT-based interventions.     

The temporal stability and predictive validity of pupils' causal attributions for difficult classroom behaviour

Background. Recent studies have investigated the causal attributions for difficult pupil behaviour made by teachers, pupils, and parents but none have investigated the temporal stability or predictive validity of these attributions. Aims. This study examines the causal attributions made for difficult classroom behaviour by students on two occasions 30 months apart. The longitudinal stability of these attributions is considered as is the predictive validity of the first set of attributions in relation to teachers' later judgments about individual students' behaviour. Sample. Two hundred and seventeen secondary school age pupils (114 males, 103 females) provided data on the two occasions. Teachers also rated each student's behaviour at the two times. Method. A questionnaire listing 63 possible causes of classroom misbehaviour was delivered to pupils firstly when they were in Year 7 (aged 11–12) and then again, 30 months later. Responses were analysed through exploratory factor analysis (EFA). Additionally, teachers were asked to rate the standard of behaviour of each of the students on the two occasions. Results. EFA of the Years 7 and 10 data indicated that pupils' attributions yielded broadly similar five‐factor models with the perceived relative importance of these factors remaining the same. Analysis also revealed a predictive relationship between pupils' attributions regarding the factor named culture of misbehaviour in Year 7, and teachers' judgments of their standard of behaviour in Year 10. Conclusion. The present study suggests that young adolescents' causal attributions for difficult classroom behaviour remain stable over time and are predictive of teachers' later judgments about their behaviour.     

Applying signal-detection theory to the study of observer accuracy and bias in behavioral assessment

We evaluated the feasibility and utility of a laboratory model for examining observer accuracy within the framework of signal-detection theory (SDT). Sixty-one individuals collected data on aggression while viewing videotaped segments of simulated teacher-child interactions. The purpose of Experiment 1 was to determine if brief feedback and contingencies for scoring accurately would bias responding reliably. Experiment 2 focused on one variable (specificity of the operational definition) that we hypothesized might decrease the likelihood of bias. The effects of social consequences and information about expected behavior change were examined in Experiment 3. Results indicated that feedback and contingencies reliably biased responding and that the clarity of the definition only moderately affected this outcome.     

Death Qualification as Systematic Exclusion of Jurors With Certain Religious and Other Characteristics

The death‐qualification process has been criticized because it tends to eliminate certain groups of individuals at a higher rate than others. This study examined whether the process systematically excludes jurors based on religious characteristics, justice philosophy, cognitive processing, and demographics. Results indicated that death qualification can be predicted by religious affiliation, devotionalism, fundamentalism, and Biblical interpretism; but not evangelism. Death qualification is predicted by the belief that murderers deserved to die, but not by beliefs that criminals deserve mercy, forgiveness, or payback. Cognitive processing had no impact on death qualification. Finally, gender and race predicted death qualification, while age and prior jury duty did not. These results are discussed in terms of implications for perceived legitimacy of the system.     

Relationships of Equality: A Camping Trip Revisited

G. A. Cohen incisively argued that our judgments of social justice should fit our convictions about how to interact with others in our personal lives. Ironically, the ordinary morality of cooperation invoked in his last book undermines his favored principle of equality, and supports John Rawls’ reliance on a relevantly impartial choice promoting appropriate fundamental interests as a basis for distributive standards. His further objections to Rawls’ account of distributive justice neglect the role of social relations in establishing the proper scope of that impartiality and the moral force of Rawls’ taxonomy of non-ideal societies. In contrast, the powerful evocation of goods of community at the end of Cohen’s last book points to a genuine inadequacy. Conscientious fellow-citizens must take account of the impact of their political choices on options for sharing and caring. In finding a proper balance between these goods and competing individualist concerns, the original position is of too little use to sustain Rawls’ assessment of his conception of justice as complete. In the face of our strong moral convictions about how to live together, both Cohen’s luck egalitarianism and Rawls’ barriers between aspirations to community and political choice must give way.
