Finkish Dispositions

Many years ago, C.B. Martin drew our attention to the possibility of 'finkish' dispositions: dispositions which, if put to the test would not be manifested, but rather would disappear. Thus if x if finkishly disposed to give response r to stimulus s , it is not so that if x were subjected to stimulus r , x would give response z ; so finkish dispositions afford a counter-example to the simplest conditional analysis of dispositions. Martin went on to suggest that finkish dispositions required a theory of primitive causal powers; there, I think, he was mistaken. All that they require is an improved conditional analysis, and this improved analysis can be built upon whatever treatments of properties and of laws we may favour on other grounds.     

Influence of Maternal Depressive Symptoms on Ratings of Childhood Behavior

This study uses information collected on two occasions from a probability sample of families with 5- to 12-year-old children (N = 1151) participating in a general population study in 1983 and follow-up in 1987. It evaluated the importance of maternal bias in the assessment of child behavior by comparing the relative strengths of association between maternal depression and childhood behavior and between maternal depression and mother reporting errors. Conduct problems and hyperactivity were measured as latent criterion variables constructed from mother, teacher, and youth (aged 12 to 16 years) ratings and their associations with maternal depression were modeled using covariance structure analysis. The analyses revealed that maternal depression was associated significantly with conduct problems ( = .35) and hyperactivity ( = .38) among 5- to 7-years-olds in 1983 but not 4 years later in 1987. None of the associations between maternal depression and mother reporting errors were significant. Among 8- to 12-year-olds in 1983, maternal depression was associated significantly not only with conduct problems ( = .17) and hyperactivity ( = .15) but also with mother rating errors of these behaviors ( = .13 and .17, respectively). Four years later in 1987 when this cohort was 12 to 16 years old, the only significant association was between maternal depression and conduct disorder ( = .25). Although evidence exists for associations between maternal depressed mood and mother rating errors, there also appears to be a substantive association between maternal depression and childhood behavior.     

Repetition priming and face processing: Priming occurs within the system that responds to the identity of a face

A familiar stimulus that has recently been recognized will be recognized a second time more quickly and more accurately than if it had not been primed by the earlier encounter. This is the phenomenon of “repetition priming”. Four experiments on repetition priming of face recognition suggest that repetition priming is a consequence of changes within the system that responds to the familiarity of a stimulus. In Experiment 1, classifying familiar faces by occupation facilitated subsequent responses to the same faces in a familiarity decision task (Is this face familiar or unfamiliar?) but not in an expression decision task (Is this face smiling or unsmiling?) or a sex decision task (Is this face male or female?). In Experiment 2, familiar faces showed repetition priming in a familiarity decision task, regardless of whether a familiarity judgment or an expression judgment had been required when the faces were first encountered. Expression decisions to familiar faces again failed to show repetition priming. In Experiment 3, familiar faces showed repetition priming in a familiarity decision task, regardless of whether a familiarity judgment or a sex judgment had been asked for when the faces were first encountered. Sex decisions to familiar faces again failed to show repetition priming. In Experiment 4, familiarity decisions continued to show repetition priming when a brief presentation time with encouragement to respond while the face was displayed reduced response latencies to speeds comparable to those for sex and expression judgments in Experiments 1 to 3. The results are problematic for theories that propose that repetition priming is mediated by episodic records of previous acts of stimulus encoding.     

Believe it or not! longer questionnaires have lower response rates

The effects of questionnaire length on response rate and response bias were examined by conducting a mail survey of 8534 persons taking distance education courses in insurance and financial planning. In 14 replications, persons were randomly assigned to receive a long or short course evaluation questionnaire. Response rate for the short form averaged about 28% higher than for the long form, and was significantly higher in all 14 replications. A measure of course satisfaction appearing on both questionnaires showed no significant differences between the long and short form in 12 of the 14 replications. The results suggested that biased measurement of consumer satisfaction does not necessarily occur on a long questionnaire with a relatively low response rate.     

Toward a profile of the female voter: Sex differences in perceived physical attractiveness and competence of political candidates

Recent national attention has focused on women's voting behavior because of this group's increasing power to determine outcomes of local, state, and national elections. Research has not established whether males and females use the same decision rules in evaluating political candidates. Because of the link between perceived physical attractiveness and many positive attributes, the present study examined sex differences in ratings of attractiveness and competence of 44 men and women in the U.S. House of Representatives. Results indicated that males and females use similar rules in evaluating male politicans' attractiveness. Women show a pro-female sentiment in evaluating female politicians' competence. Physical attractiveness was positively related to perceived competence for both male and female politicians. Contrary to previous research, women voters showed a marked pro-female sentiment, and men were neutral, evaluating male and female politicians similarly.     

Left hemisphere superiority for pronounceable nonwords,but not for unpronounceable letter strings

Right-handed adults were asked to identify bilaterally presented linguistic stimuli under three experimental conditions. In Condition A, stimuli were three-letter pronounceable nonwords (such as TUP), and subjects were asked to report them by naming them. In Condition B, stimuli were three-letter pronounceable nonwords, and subjects were asked to report them as strings of letters. In Condition C, stimuli were more or less unpronounceable letter strings (such as UTP) created by rearranging the letters of pronounceable nonwords, and subjects reported them as strings of letters. Pronounceable nonwords were found to be better identified from the right visual hemifield irrespective of the way in which they were reported. Unpronounceable letter strings did not produce any visual hemifield difference. Nonwords are of interest because they can be seen as potential words that lack both specific semantic properties and entries in the subject's internal lexicon. The results of the experiment are consistent with the view that both the left and right cerebral hemispheres are able to identify letters but the left hemisphere is more sensitive to the pronounceability of the nonwords. This may happen either because the left hemisphere can make better use of resemblances to real words or because it has access to spelling to sound correspondence rules.     

Central auditory processing: I. Ear dominance—A perceptual or an attentional asymmetry?

The phenomenon of ear dominance for pitch described by Efron and Yund has been attributed by them to an asymmetry of sensory origin in the binaural integration of dichotic tone pairs. An explanation of this phenomenon in terms of an attentional bias is rejected on the basis of two experiments where the possibility of such bias was excluded. These and other experiments indicate that a simple explanation of this ear dominance in terms of a hemispheric specialization in the processing of tonal stimuli also must be rejected.
