Reliability of the Finger Tapping Test and a note on sex differences.

The reliability of the Finger Tapping Test was investigated in two studies. In the test-retest condition 30 male and 30 female college students were tested twice by the same examiner. In the inter-examiner condition 30 male and 30 female college students were tested once by each of two examiners. Reliability coefficients for the dominant and nondominant hands were high in both studies (about .8), as contrasted with that of the ratio score (about .5), casting doubt on the use of the ratio score to lateralize impairment. Significant sex differences (males about 3 taps faster) were found, calling into question the use of single test interpretation schemes. Slight inter-examiner differences in mean scores were also detected.     

Testable conditions for triads of paired comparison choices

Forty-two choice models, each representing stimuli by one-dimensional probability distributions, are obtained by relaxing the assumptions of Thurstone's Case V Law of Comparative Judgment. The models which imply or fail to imply each of nine testable probabilistic conditions are determined. Stochastic transitivity is vulnerable in most of these models. The results suggest discarding weak stochastic transitivity, and in its place using the conjunction of weak stochastic transitivity and the triangular condition. However, unless it is possible to predict which stimuli will produce violations of the conditions, none of the conditions can be rejected on the basis of too frequent intransitive triads of choices.I am grateful to the referees, and to J. H. Griesmer and C. H. Coombs for a number of helpful criticisms and comments. J. H. Griesmer suggested a proof of Theorem 9, and a referee suggested a more direct proof of Theorem 5. A proof of Theorem 5 and the result concerning a maximally intransitive judge were given in [18].     

Mind, World and Language: McDowell and Kovesi

The ideas of John McDowell concerning the relations between mind, world and language are brought into contact with those of Julius Kovesi, with a view to seeing whether the latter can illuminate and flesh out the former. McDowell's dialectic in Mind and World is expounded and reviewed, hinging on the notion of 'conceptual second nature' as his suggested way of showing that there is nothing mysteriously non–natural in human animals learning to find their way about both in a world characterised by lawlike connections and in one characterised by rational connections. Kovesi's redrawing, in Moral Notions , of the Aristotelian material/formal metaphysical distinction as one between the logical elements of concepts, is adduced to show how the world is 'shot through' with concepts and reasons: the formal elements of concepts are nothing other than the reasons we have for collecting varied features of the material world under a concept, to meet our bodily and social needs. The mind can then be treated as a set of acquired capacities and dispositions to become conversant with these features and with the corresponding needs. Some possible objections to this bringing together of the two sets of ideas are briefly examined, and overall conclusions drawn.     

Threat processing in obsessive-compulsive disorder: evidence from a modified negative priming task

Individuals with obsessive-compulsive disorder (OCD) often experience intrusive thoughts. These intrusions may be due to biases in information processing mechanisms, including attention, memory, and learning. To examine this hypothesis, we presented a modified negative priming (NP) paradigm with idiographically selected words to 19 individuals with OCD (OCs) and 19 matched non-anxious control participants (NACs). The words included OCD-relevant threat, OCD-relevant positive, and neutral words. This paradigm typically elicits positive priming because participants may learn the contingency between the prime and probe that facilitates responding [Frings and Wentura (2006). Strategy effects counteract distractor inhibition: NP with constantly absent probe distractors. Journal of Experimental Psychology: Human Perception and Performance, 32, 854-864]. As predicted, NACs showed facilitation (i.e., positive priming) rather than NP for all word types, whereas OCs exhibited facilitation for only neutral words. For positive words, OCs exhibited no priming and for threat words they exhibited NP. These results suggest that for idiographic, OCD-relevant threat information, individuals with OCD show difficulty learning the contingency between the information in the prime and probe displays relative to the NACs.     

The effects of realistic threat and group identification on social dominance orientation

Based on social identity and intergroup threat theories, we argue that social dominance orientation (SDO) can increase as a result of realistic threat, or perceived obstacles to the ingroup’s position and general welfare. However, this effect should be strongest among highly-identified group members, who are particularly concerned with protecting their ingroup against threat. Study 1 found that among non-Asian Americans, racial group identification moderated the relationship between perceptions of realistic threat from Asian Americans and SDO. Study 2 replicated Study 1 using an experimental, rather than correlational, design. Using different social groups, Study 3 showed that non-science college majors who identified strongly with their field of study exhibited higher SDO after being made to feel threatened by science majors. The results from these studies have implications for research on the meaning and antecedents of SDO.     

Group status, perceptions of threat, and support for social inequality

Members of high-status groups have been shown to favor social inequality, but little research has investigated the boundary conditions of this phenomenon. In the present article we suggest that perceived intergroup threat moderates the relationship between group status and support for social inequality (i.e., social dominance orientation), especially among highly identified group members. In Study 1, Democrats and Republicans rated their party’s relative status and were later exposed to a leading US. Presidential candidate from the opposing party (high threat) or their own party (low threat). In Study 2, university students were made to believe that their school had high or low status and were then presented with threatening or non-threatening information about a rival institution. The results of both studies supported the prediction that status only increases preferences for group-based inequality under conditions of high threat and high ingroup identification.     

Models,measurement and computer simulation: the changing face of experimentation

The paper presents an argument for treating certain types of computer simulation as having the same epistemic status as experimental measurement. While this may seem a rather counterintuitive view it becomes less so when one looks carefully at the role that models play in experimental activity, particularly measurement. I begin by discussing how models function as “measuring instruments” and go on to examine the ways in which simulation can be said to constitute an experimental activity. By focussing on the connections between models and their various functions, simulation and experiment one can begin to see similarities in the practices associated with each type of activity. Establishing the connections between simulation and particular types of modelling strategies and highlighting the ways in which those strategies are essential features of experimentation allows us to clarify the contexts in which we can legitimately call computer simulation a form of experimental measurement.

Significant other primes and behavior: motivation to respond to social cues moderates pursuit of prime-induced goals

Significant others can automatically activate a variety of goals, including goals that significant others have for an individual and the individual's personal goals that are associated with the significant others. Across three studies, this article shows that the effects of significant other primes (i.e., mother, roommate) on behavior depend on individual differences in both personal goals and responsiveness to social cues (i.e., self-monitoring, need to belong). Specifically, individuals who are motivated to respond to social cues assimilate to a goal that their primed significant other has for them, regardless of whether they personally hold the goal. Individuals not so motivated, on the other hand, assimilate to the goal only when it is one that they also personally hold. Implications of these findings for research on the prime-to-behavior relationship and interpersonal goal pursuit are discussed.
