Animal phobias versus claustrophobias: Exteroceptive versus interoceptive cues

The overall purpose of this investigation was to examine heterogeneity among specific phobias. In particular, the goals were to compare features of fear responding between individuals fearful of claustrophobic situations and individuals fearful of spiders/snakes, and to compare their response to hyperventilation challenges. By so doing, specific predictions were tested in relation to a conceptual model of exteroceptive and interoceptive fear cues. Using a nonclinical sample, 19 subjects with spider/snake phobias, 18 nonphobies, and 9 subjects with claustrophobias were exposed on two separate occasions to a live tarantula or python, a small closet, and a hyperventilation challenge. Dependent measures included subjective anxiety, panic attacks, physical symptoms, cognitive symptoms (or, fear of symptoms) and heart rate. In addition, subjects completed a standardized self-report scale that measures fear of bodily symptoms of arousal. It was found that subjects with claustrophobia reported more physical symptoms and cognitive symptoms than did subjects with snake/spider phobias, in response to their fear-relevant stimulus. In addition, claustrophobic subjects were more fearful of hyperventilation challenges and reported more fear of bodily symptoms, than did snake/spider phobic subjects. Finally, subjects with claustrophobia were as fearful of hyperventilation as they were of their fear-relevant stimulus. Theoretical and empirical implications of these findings are discussed.     

Children''s self-initiated approach to spiders

Seventeen school children were invited to stay in the presence of a harmless spider for 4 minutes under instructions which were designed mildly to encourage touching the spider but which left open a clear alternative of not touching. Subjects confronted the spider in dyads which differed in composition in terms of fear-level and sex of subjects. The main finding was that boys did not show any more approach when paired with girls, thus confirming previous negative findings in this regard. Other findings were that boys showed more approach than girls, level of fear interacted with sex of subject, and ‘fearless’ but not ‘fearful’ subjects showed more approach with repeated experience.     

Sex Differences in Visual Recognition Memory: Support for a Sex-Related Difference in Attention in Adults and Children

The selectivity hypothesis of Meyers-Levy (1989) proposes that cognitive sex differences reflect underlying differences in information processing between males and females. Males are considered to be more likely to organize information in a self-related manner, whereas females are more likely to adopt a comprehensive approach to information processing. We tested this hypothesis in children (10–15 years) and adults using recognition memory tasks. Tests were devised which employed male-oriented objects, female oriented objects, or random objects. In both the child and adult samples, females performed significantly better than males on tests using random and female-oriented objects. Males performed at the level of females only when tested for recognition of male-oriented objects. These results demonstrate that this sex difference is present prior to puberty and support the concept of sex differences in information processing.     

Towards an empirical definition of courage

Receiving attribution of courage or bravery is important to most of us. Three possible modes of attribution are outlined, two of which are taken to be naive (i.e., attributing bravery if one is afraid oneself or identifying bravery with fearlessness), only one is taken as sophisticated i.e., bravery as a result of approach by a fearful person. Inferences about the use of these modes are made on the basis of correlational patterns in the data of adolescent subjects who watched snake-handling by a filmed actor/actress. Subjects rated themselves for hypothetical fear (if they had had to handle the snake): in addition they rated the handler on fear or bravery. Results suggested an increasing use of the sophisticated mode of attribution with increasing age. Clear use of the sophisticated mode however was not demonstrated in the case of attributing to female actresses. Possible interpretations of this sex of attributee effect are taken up in the Discussion.     

Effects of male pre-ejaculatory vocalizations on female receptive behavior in the rat (Rattus norvegicus)

Both male and female rats (Rattus norvegicus) emit ultrasounds during copulation. Bursts of ultrasounds from males that occur as ejaculation approaches are lower in frequency, longer in duration, and louder than those that appear earlier in the ejaculatory series. We attempted to determine if these pre-ejaculatory calls affect female sexual behavior. The behavior of females paired with devocalized males was compared with that of females paired with intact males, and in a second experiment tape-recorded vocalizations were played to females paired with devocalized males. Females were less receptive when paired with devocalized males; they were less likely to remain stationary when males attempted to mount. Playback of both types of calls restored female immobility toward control levels, although pre-ejaculatory calls were more effective than mating ones. Pre-ejaculatory calls restored running and training levels somewhat toward control level but to a lesser extent than female immobility.     

Serpent versus surrogate and other determinants of runway fear differences

Avoidance behavior and fear ratings by snake-fearful college volunteers were studied as a function of live vs stuffed snake stimuli, order of presenting the snakes, accompanied (participant modeling format) or unaccompanied social context in the runway test, high or moderate initial fear level and sex of subject. The live snake sponsored more avoidance and rated fear than the specimen, and type of snake stimulus interacted with students' initial fear levels, thus raising questions about previous research using specimens instead of live phobic animal stimuli. Accompanied social context produced generally less fear and avoidance than unaccompanied approach. Numerous complex interactions were found among the type of snake, presentation sequence, social context, sex and fear level variables, raising methodological cautions for future research.     

Issues in the assessment of fear: Response concordance and prediction of avoidance behavior

A large group of female subjects completed a battery of questionnaires including the Fear Survey Schedule and the Snake Questionnaire. They were later administered a behavioral approach test with a live snake during which self-report, behavioral, and psychophysiological measures were collected. These data were initially used to test Hodgson and Rachman's (Behavior Research and Therapy, 1974,12, 319–326) hypothesis that response concordance varies directly with the strength of emotional arousal. The results indicated that the less fearful subjects produced a greater degree of response concordance—contrary to the hypothesis. Next, previously identified factors extracted from the Snake Questionnaire were examined to determine their ability to predict behavioral avoidance during the test procedure. One factor was suitably predictive of the avoidance criterion. These two sets of results are discussed in terms of a possible explanation for concordance variations and in terms of the potential value of factor scores in subject selection and fear assessment.     

Blood/injury fear, fainting and avoidance of medically-related situations: a family correspondence study

The relationship of mutilation fear and fainting was examined in 204 students, (103 fainters and 101 non-fainters) by administering a series of questionnaires and a structured interview concerning the history, effects and circumstances of their fear and fainting. Two hundred and sixty of their parents completed the same scales along with a self-report version of the structured interview. Subjects were classified according to their fainting status and level of fear based on Mutilation Questionnaire scores, as phobic, fearful, and non-fearful fainters, and fearful non-fainters. Phobic and fearful fainters avoided significantly more medical and related situations due to their fear and fainting than fearful non-fainters and non-fearful fainters. Medical avoidance was best predicted by a linear combination of subjects' estimated probability of future fainting and number of past faint episodes. More females reported fainting and females reported greater fear, but they did not differ from males in fear-motivated avoidance of medical situations. A significant parent-child correspondence was found for fainting, but not for fear nor for avoidances. Implications of these findings for fear and fainting acquisition and its relation to avoidance were discussed.     

The application of reinforcement and participant modeling procedures in the treatment of snake-phobic behavior

In Experiment I, one group of snake phobic Ss was reinforced (with tokens) for approaching a harmless snake. A second group received token reinforcement on a non-contingent basis, in the same setting, with a third group serving as non-treated controls. Although slight improvement was noted for all three groups, the groups did not differ significantly with respect to an increase in approach behavior or a reduction in subjective fear rating. A fourth group of snake phobic Ss was reinforced with money for approaching the snake, but showed no more improvement than the other three groups. In Experiment II. Ss who had participated in Experiment I were assigned to a participant modeling (P-M) group, in which they observed a fearless model interact with a snake and were subsequently guided through similar interactions with the snake, or to a non-treated control group. The P-M Ss showed a very marked decrement in snake phobic behavior (which generalized to a non-treatment snake) following the 40-min treatment, in contrast to control Ss who showed virtually no change.     

Adult attachment and patterns of extradyadic involvement

Relationships between patterns of extradyadic involvement (EDI) and adult attachment were examined separately with undergraduates and community adults reporting prior EDI. Those with fearful or preoccupied styles reported more intimacy motivations for EDI, and undergraduates with these styles also reported more self-esteem motivations. Conversely, those with a dismissive style reported more autonomy motivations for EDI. Those with a fearful attachment style reported ambivalence about intimacy in the EDI. Fearful and preoccupied undergraduates and community males reported a more obsessive extradyadic relationship. However, dismissive individuals did not report more casual EDI. Gender effects also emerged, with females reporting more intimacy motivations than males, and undergraduate males reporting more casual EDI than undergraduate females. In the undergraduate sample, dismissive males had the most extradyadic partners over the prior 2 years relative to all other groups, and preoccupied females reported more partners than secure females. Clinical implications of these findings are discussed.     

MALE AND FEMALE PERSONAL SPACE NEEDS AND ESCAPE REACTIONS UNDER INTRUSION: A TURKISH SAMPLE

Two experiments were conducted to determine the personal space needs of Turkish males and females, and their reactions to intruders of this space in same- and opposite-sex pairings. In experiment 1, the seating distances were measured for 32 male and 32 female undergraduate students on a bench already occupied by another person of either the same or opposite sex in a bogus experiment on line judgements. In experiment 2, 60 male and 60 female library users were observed under three conditions; (a) intrusion, (b) no-intrusion, and (c) control. The results of both studies indicated that female subjects used larger distances when paired with a person of the opposite sex, and got up to leave their seats more often and earlier in the condition of intrusion by a male than a female. In same-sex pairings, males were found to use somewhat larger distances and react faster to intrusions than females, but the differences between the two sexes did not reach statistical significance.     

Cognitions and courage in the avoidance behavior of acrophobics.

Fifty subjects (29 fearless and 21 fearful) were tested in a potentially acrophobia-inducing situation, and their avoidance behavior and self-reported fear were noted. Subjects also completed various scales intended to measure their fearfulness and thoughts in hypothetical height-phobic, social-phobic and nonphobic situations. Interviews conducted immediately after the behavioral test, evaluated their thinking, fearfulness and tactics designed to deal with any fear they experienced. Analyses indicated that catastrophic thinking is more evident than irrational thinking in height situations and that such thinking was the best predictor of behavior among the measures used. The results are discussed in terms of their relevance for cognitive views of acrophobia and in terms of their relevance for treatment.     

The Development and Sex-Related Use of Interruption Behavior

In this article the authors argue that claims of sex differences in interruption behavior should not be uncritically accepted as there are limitations in previous research that make such acceptance questionable. The frequency of interruption was examined over a portion of the early life span (Grades 4 and 9 and college). Twenty-minute structured conversations of 90 dyads (30 male, 30 female, and 30 mixed sex) were scored for four types of interruption, and both developmental and sex differences in interruption behavior were examined. Interruption frequency did not change over age or across dyads of different sex composition. Males did not interrupt any more than females did and females were interrupted by their partners as frequently as males were interrupted by theirs, with one exception: Grade 9females were interrupted more by their female partners. Interruptions were asymmetrically distributed in same-sex and opposite-sex dyads; however, the asymmetry in opposite-sex dyads was not predictablefrom sex of subject or sex of partner. That is, males did not interrupt females any more than females interrupted males. The authors conclude that wholesale acceptance of sex differences in interruption behavior is not warranted.     

The effects of instructions, level of fear, duration of exposure and repeated measures on the Behavioral Avoidance Test

This research studied the effects of level of fear, instructions, duration of each step and the effect of retest on the performance of subjects on a Behavioral Avoidance Test of a harmless snake. Results showed a significant effect of the level of fear. instructions, and effect of retest on the performance of these subjects. An interaction between level of fear and instructions was also found for a proportion of subjects manipulating the snake. This interaction indicated that moderately afraid subjects were relatively more influenced by the instructions than very afraid subjects.     

Does fear modulate defensive and offensive types of maternal attack in mice?

Swiss CD‐1 lactating mice show a different pattern of attack toward intruders of differing sex, displaying defensive attack against the male (bites on the head and ventrum associated with fear) and offensive attack against the female (bites on the back and flanks with no elicitation of fear). This dichotomy may reflect diverse functions of maternal aggression: the attack toward males (the more infanticidal gender in laboratory strains) has been interpreted as a counterstrategy to infanticide, whereas the attack toward females may serve to establish a social hierarchy or to space rivals of the same sex. In terms of proximal mechanisms, fear may be a key factor involved in the modulation of the different patterns of attack. In Experiment 1 we compared the pattern of attack of lactating females in Swiss CD‐1 and Wild mice toward male and female intruders in relation to fear components of behavior of the attacking dams. Results showed that in Swiss mice, male intruders were attacked with a defensive type of attack accompanied by high levels of fear, whereas female intruders did not elicit fear in the attacking animal but were attacked with an offensive pattern. In Wild mice, both types of intruders were attacked with a defensive pattern; notwithstanding, fear was evident only toward male intruders. This suggests that fear is not totally responsible for the expression of the defensive type of attack. To test the hypothesis that defensive attack toward male and female intruders may be related to the infanticidal potential of the intruder, Experiment 2 examined levels of infanticide in both male and female Swiss CD‐1 and Wild mice. Swiss female mice showed virtually no infanticidal behavior, whereas Swiss males and both sexes of Wild mice showed similarly high levels of infanticide (55%–75%). From a game theory perspective, the defensive pattern of maternal attack toward female intruders in Wild mice is discussed as “extreme” defense of a high value resource and thus, functionally, a competitive form of aggression.

An investigation of vocational indecision in college students: Correlates and moderators

This study investigated the relationships among fear of success, locus of control, and vocational indecision in college students and the extent to which these relationships are moderated by sex and ability. Subjects, 103 female and 98 male undergraduate students, were administered measures of fear of success, locus of control, and career indecision. In addition, American College Test (ACT) composite scores were available for 154, or 77%, of the subjects. Results indicate that vocationally undecided college students are more external in their locus of control, are more fearful of success, and have lower ACT scores than decided students. Multiple regression analyses for the prediction of vocational indecision yield mixed results, as the power of prediction of the independent variables of locus of control and fear of success were influenced by the sex and ability level of the student. Results, implications for future vocational indecision research, and implications for counseling assistance of vocationally undecided students are discussed.     

Self-report and physiological changes accompanying repeated imagining of a phobic scene.

Twenty female subjects were selected from a larger subject pool on the basis of their scores to the ‘snakes’ item on the Geer (1965) Fear Survey Schedule. Ten of the subjects were selected as phobic; the other ten were non-phobic controls. Heart rate, skin conductance and self-reports of fear and imagery vividness were continuously monitored while subjects repeatedly imagined a prescribed snake scene for a total of 15 trials. The phobic group reported more overall fear to the images. Further, while the nonphobic subjects reported progressively less fear over trials, the phobic subjects reported progressively more fear. The groups did not differ in rated imagery vividness. However, heart rate responses to the image differentiated the two groups. The non-phobic subjects showed a progression from cardiac acceleration in the early trials to a biphasic response pattern, deceleration preceding acceleration, in the later trials. In contrast, the phobic subjects demonstrated sustained acceleration in the later trials. The groups did not differ in skin conductance response amplitude.     

Sex, sex-role identification, and awareness of sex-role stereotypes

An experiment was run to determine if androgynous people have transcended traditional sex roles or merely incorporated both sex roles into their repertoire. Masculine sex-typed, feminine sex-typed, and androgynous people listed as many masculine and feminine stereotypes as they could think of in a time-limited task. Highly sex-typed individuals showed more awareness of their own sex's attributes than the other sex's stereotypes. Androgynous people showed greater awareness of both sexes' attributes as compared with sex-typed people, indicating support for the incorporation hypothesis rather than the transcendance hypothesis. However, the stereotypes androgynous people listed were somewhat less evaluative in tone compared with those of sex-typed people, Overall, subjects listed more stereotypes of females than males, and female stereotypes were more negative than male stereotypes.     

Fear of failure and student athletes’ interpersonal antisocial behaviour in education and sport

Background. The link between fear of failure and students’ antisocial behaviour has received scant research attention despite associations between fear of failure, hostility, and aggression. Also, the effect of sport experience on antisocial behaviour has not been considered outside of the sport context in adult populations. Further, to date, sex differences have not been considered in fear of failure research. Aims. To examine whether (a) fear of failure and sport experience predict antisocial behaviour in the university and sport contexts in student athletes, and whether this prediction is the same in males and females; and (b) sex differences exist in antisocial behaviour and fear of failure. Sample. British university student athletes (n= 176 male; n= 155 female; M_age= 20.11 years). Method. Participants completed questionnaires assessing fear of failure, sport experience, and antisocial behaviour in both contexts. Results. (a) Fear of failure and sport experience positively predicted antisocial behaviour in university and sport and the strength of these predictions did not differ between males and females; (b) females reported higher levels of fear of devaluing one's self‐estimate than males whereas males reported higher levels of fear of important others losing interest than females. Males engaged more frequently than females in antisocial behaviour in both contexts. Conclusions. Fear of failure and sport experience may be important considerations when trying to understand antisocial behaviour in student athletes in education and sport; moreover, the potential effect of overall fear of failure and of sport experience on this frequency does not differ by sex. The findings make an important contribution to the fear of failure and morality literatures.
