A Goal‐Activation Framework of True and False Intentions

We propose a novel cognitive framework to distinguish between statements of true and false intent based on research on goal‐directed behaviour. A true intention comes with a commitment to carry out the stated intention. This commitment activates the behavioural goal of a true intention. In contrast, a false intention does not come with a commitment to carry out the stated intention. Hence, the behavioural goal of a stated false intention should be inactive. Active goals have profound and predictable influences on human behaviour. For instance, active goals influence planning, future thought and evaluations. Such influences are functional—they aid in goal attainment. Insofar as true intentions activate goals, but false intentions do not, the expected influences of active goals should be weaker or non‐existent for those stating a false intention. The framework parsimoniously accounts for previous intention‐focused deception studies while generating new directions for future research.Copyright © 2017 John Wiley & Sons, Ltd.     

A Comparison of Eating Disorder Symptomatology, Role Concerns, Figure Preference and Social Comparison Between Women Who Have Attended Single Sex and Coeducational Schools

This study sought to examine the effect of high school gender composition on eating disorder symptomatology and attitudes of female Australian university students. We compared female students who had previously attended single sex (n?=?52) or coeducational (n?=?43) high schools on measures of eating disorder symptomatology, role concerns, figure preference and social comparison so as to examine the effect of high school gender composition on these measures. Importantly, the groups compared here were not significantly different in age, body mass index, socioeconomic status, or whether they had previously sought advice about their weight. Contrary to predictions based on previous research, there were no significant differences between the groups on eating disorder symptomatology, role concern, or social comparison measures. However, students who had previously attended single sex schools endorsed significantly thinner figure preferences overall, suggesting that school environment was an important cultural factor in the development of aspiration towards a thin idea. Additionally, both groups perceived their current figure to be larger than the figure they perceived as most attractive. Our findings provide mixed support for the notion that high school gender composition impacted on the eating-related behaviour and attitudes of university students. Methodological differences that may account for the discrepancies between the findings of the current study and those of earlier work are discussed. Further research including longitudinal studies that employ larger sample sizes is required to clarify these findings.     

Avoidance ratings and fears of Chinese adults by age, ethnic group, sex, and residency

Few studies among the Chinese population concerning avoidance out of fear have been reported. Existing studies are limited to school and collegiate samples while overlooking ethnic minorities, of which China has more than 50. In this study, a general population sample in China indicated the level at which they would avoid certain situations. The data were analyzed relative to age, ethnicity, sex, and the amount of time living in urban or rural areas. Three samples (urban Han, n=144; rural Han, n=144; Urban Hui, n=72) were selected using stratified quota sampling. Respondents identified that they avoided social situations the most and agoraphobic situations the least. Overall, women expressed significantly greater fear. This sex difference was less marked in the urban sample where the Chinese tradition of male dominance has been diluted due to urbanization and modernization. There were few age-related differences, although some fears among the elderly were explained by age-related vulnerabilities and folklore. The Hui minority group had significantly lower overall scores than the Han group; this was attributed to the role of their Islamic beliefs.     

Relations of socioeconomic status and sex variables to the complexity of worker functions in the occupational choices of elementary school children

The relationships of sex and socioeconomic status to complexity of worker functions in the occupational choices of elementary school children were studied. Complexity of worker functions was defined in terms of the most complex level of interaction required of a worker, when interacting with data, people, and things. The children included in the study were third- and fifth-grade students, divided on the basis of grade, sex, and socioeconomic status. The children's occupational choices were scored for complexity with the code numbers of the worker function hierarchies of the U.S. Employment Service's Dictionary of Occupational Titles (Washington, D.C.: U.S. Govt. Printing Office, 1977, 4th ed.). Findings based on the obtained data indicated the following: (a) a positive relationship between socioeconomic status and complexity of data manipulation in occupational choices; and (b) greater complexity of interaction with things in the occupational choices of boys, than girls. The positive relationship between socioeconomic status and complexity of data manipulation was accounted for by the children's exposure to their parents' orientation toward data manipulation. Apparent differences in the play activities of boys and girls was used to explain differences between the sexes in the levels of complexity of interactions with inanimate objects and animals.     

Topography of signal-centered behavior in the rat: Effects of deprivation state and reinforcer type

In a series of three experiments, groups of food-deprived and water-deprived rats were given pairings of a retractable lever (CS⁺) with response-independent deliveries of either solid or liquid reinforcers. In Experiment 1 food-deprived rats given a solid-pellet reinforcer differentially tended to sniff, paw, mouth, and bite the CS⁺ lever more often than a lever that was not paired with food (CS⁻), whereas food-deprived rats given a liquid reinforcer tended to differentially sniff, paw, and lick the CS⁺ lever. 23½-hour water-deprived rats given liquid reinforcers showed very little CS⁺ contact. In Experiment 2 increasing the severity of water deprivation from 23½ to 47½ hours significantly increased CS⁺ contact. In Experiment 3, subjects that were simultaneously food and water deprived and given a water reinforcer failed to exhibit differential CS⁺ contact, but subjects that were simultaneously food and water deprived and given a food reinforcer did acquire differential CS⁺-contact behavior. These results suggest that (a) even under a single motivational state the nature of signal-centered behavior can be determined by type of reinforcer, (b) although water reinforcement produces less signal contact than food reinforcement, this can be facilitated with more severe water-deprivation levels, and (c) high CS-contact rates using food reinforcement are not simply a product of reductions in body weight with food deprivation.     

Reevaluating evaluative conditioning: a nonassociative explanation of conditioning effects in the visual evaluative conditioning paradigm.

In 2 studies, the authors investigated whether evaluative conditioning (EC) is an associative phenomenon. Experiment 1 compared a standard EC paradigm with nonpaired and no-treatment control conditions. EC effects were obtained only when the conditioned stimulus (CS) and unconditioned stimulus (UCS) were rated as perceptually similar. However, similar EC effects were obtained in both control groups. An earlier failure to obtain EC effects was reanalyzed in Experiment 2. Conditioning-like effects were found when comparing a CS with the most perceptually similar UCSs used in the procedure but not when analyzing a CS rating with respect to the UCS with which it was paired during conditioning. The implications are that EC effects found in many studies are not due to associative learning and that the special characteristics of EC (conditioning without awareness and resistance to extinction) are probably nonassociative artifacts of the EC paradigm.     

Effects of reinforcement magnitude on interval and ratio schedules

Rats' lever pressing was studied on three schedules of reinforcement: fixed interval, response-initiated fixed interval, and fixed ratio. In testing, concentration of the milk reinforcer was varied within each session. On all schedules, duration of the postreinforcement pause was an increasing function of the concentration of the preceding reinforcer. The running rate (response rate calculated by excluding the postreinforcement pauses) increased linearly as a function of the preceding magnitude of reinforcement on fixed interval, showed slight increases for two of the three animals on response-initiated fixed interval, and did not change systematically on fixed ratio. In all cases, the overall response rate either declined or showed no effect of concentration. The major effect of increasing the reinforcement magnitude was in determining the duration of the following postreinforcement pause, and changes in the response rate reflected this main effect.     

The effects of cued UCS rehearsal on the retention of differential 'fear' conditioning: an experimental analogue of the 'worry' process

This study describes a human electrodermal conditioning experiment in which subjects were asked to mentally rehearse the UCS in a period following initial fear conditioning and prior to a test period involving nonreinforced presentations of the CS. Subjects who were asked to rehearse the UCS retained a differential fear CR during subsequent unreinforced presentations of the CS, but control subjects who were asked to rehearse either a nonaversive event or an aversive event unrelated to the UCS failed to retain the differential CR they had acquired during conditioning. These results suggest that rehearsal of the UCS during periods when CS and UCS are absent can aid the persistence of a fear CR in the absence of further pairings of the CS and UCS. It is argued that these effects can be explained in terms of the effect of UCS rehearsal on the strength and evaluation of the UCS representation. It is also suggested that cued UCS rehearsal might provide a useful procedure for understanding clinical incubation effects and for understanding how the 'worry' process contributes to the maintenance and incubation of fear.
