How meaning shapes seeing

Inattentional blindness refers to the failure to see an unexpected object that one may be looking at directly when one's attention is elsewhere. We studied whether a stimulus whose meaning is relevant to the attentional goals of the observer will capture attention and escape inattentional blindness. The results showed that an unexpected stimulus belonging to the attended semantic category but not sharing physical features with the attended stimuli was detected more often than a semantically unrelated stimulus. This effect was larger when the unexpected stimuli were words than when they were pictures. The results imply that the semantic relation between the observer's attentional set and the unexpected stimulus plays a crucial role in inattentional blindness: An unexpected stimulus semantically related to the observer's current interests is likely to be seen, whereas unrelated unexpected stimuli are unseen. Attentional selection may thus be driven by purely semantic features: Meaning may determine whether or not one sees a stimulus.     

Latent timing in human conditioned avoidance

Four experiments explored signal timing in human conditioned avoidance. Participants received discrimination training with different duration signals that announced the outcome (S+) or not (S-). Temporal discrimination and superposition of performance to S+ signals of different length (3, 6, or 9 s) was found both in within-subjects (Experiment 1a) and between-subjects (Experiment 1b) designs. S- signals also produced a temporal discrimination and superposition effect during a single test trial conducted after the meaning of the signals was reversed through instructions. Experiments 2a and 2b replicated these results in a situation in which (a) the durations of the S+ and S- signals were different (4.5 or 9 s) to prevent any temporal generalization between them (Experiment 2a), and (b) only S- signals were presented during training, precluding developing of inhibition to S- (Experiment 2b). These results show that participants time both S+ and S- signals in human conditioned avoidance, and they further suggest that the timing of a cue is independent of reinforcement.     

The Effect of Interpersonal Touch During Childhood on Adult Attachment and Depression: A Neglected Area of Family and Developmental Psychology?

Interpersonal touch has been little studied empirically as an indicator of parent- and peer-child intimacy. Undergraduate students (n = 390) were studied using a questionnaire survey regarding the frequencies of interpersonal touch by father, mother, same-sex peers, and opposite-sex peers during preschool ages, grades 1–3, grades 4–6, and grades 7–9, as well as their current attachment style to a romantic partner and current depression. A path model indicated that current depression was influenced significantly by poorer self- and other-images as well as by fewer parental interpersonal touches throughout childhood. Other-image was influenced by early (up to grade 3) parental interpersonal touch. Our findings suggest that a lower frequency of parental touching during childhood influences the development of depression and contributes to a poorer image of an individual’s romantic partner during later adolescence and early adulthood.     

The Official Torturer: A Learning Model for Obedience to the Authority of Violence

The military training and selection procedures leading to the behavior of a torturer are discussed. The analysis is based on testimonies of army police servicemen at the first torturers' trial in Greece and on the interviews of ex-military policemen who served under the military dictatorship in Greece (1967–1974). It is concluded that, given the appropriate training condition, any individual is a potential torturer, and a model for obedience to the authority of violence is proposed.     

Optimism and pessimism as predictors of change in health after death or onset of severe illness in family.

The authors prospectively examined changes in health after a major life event (death or onset of severe illness in family) among 5,007 employees (mean age=44.8 years) whose optimism and pessimism levels were assessed in 1997 and major life events in 2000. Health was indicated by sickness absence days during a period covering 36 months prior to the event and 18 months after the event. Increase in sick days after the event was smaller and returned to the prevent level more quickly among highly optimistic individuals than among their counterparts with low optimism. Parallel changes were not observed in relation to pessimism. These findings suggest that optimism may reduce the risk of health problems and may be related to a faster recovery after a major life event.     

Cognition and incident coronary heart disease in late midlife: The Whitehall II study

The purpose of this study was to investigate whether cognitive function in midlife predicts incident coronary heart disease (CHD), followed up over 6 years. Data on 5292 (28% women, mean age 55) individuals free from CHD at baseline were drawn from the British Whitehall II study. We used Cox regression to model the association between cognition and CHD in analyses adjusted for socio-demographic variables, cardiovascular risk factors and health behaviors. The results show a one standard deviation lower score on the “general” cognitive measure and measures of reasoning and vocabulary to be associated with elevated CHD risk. There was some evidence that these effects differed between high and low socioeconomic status (SES) groups with associations only seen in the low SES group. These results were not explained by threshold effects or by the different SES groups representing different parts of the cognitive test score distribution. Three other possible explanations of these results are discussed: sub clinical vascular disease drives the observed association but no effect is observed in the high SES group due to compensation provided by greater cognitive reserve, cognition is a marker of overall bodily integrity particularly in low-SES groups, and SES is a moderator of the association between cognition and CHD, because it marks a range of other risk factors.     

EAS temperaments as predictors of unemployment in young adults: A 9-year follow-up of the Cardiovascular Risk in Young Finns Study

EAS temperament traits (negative emotionality, activity, sociability) are known to be associated with psychosocial adjustment. We examined whether these traits also predict unemployment in young adults. The participants (n = 1493–1893) were from the population based Cardiovascular Risk in Young Finns Study. EAS temperaments were assessed three times during a 9-year period from 1992 to 2001. Unemployment status and duration of unemployment were assessed in 2001 when the participants were from 24- to 39 -year olds. Especially higher negative emotionality and lower activity were associated with greater likelihood of reporting unemployment at the end of the follow-up. Higher negative emotionality and lower sociability and lower activity predicted unemployment duration. These results suggest that temperament traits are associated with risk of unemployment.
