A comparison of parent-education methods in maternity wards

This study investigated the effect of three parent-education methods for use with mothers in maternity wards. The three methods were videotapes and a handbook, videotapes only, and handbook only. The two groups who received the videotapes performed better on a posttest than two no-treatment control groups. No differences were evident between the videotapes and handbook group and the videotapes-only group. The handbook-only condition was better than only one of the control groups. Usefulness of the program, problems encountered, and future research needs are discussed.     

Teaching generalization of purchasing skills across community settings to autistic youth using videotape modeling.

Three young autistic adults were trained to purchase items. Training was conducted in one setting with concurrent generalization probes taken in three community stores. Training in one setting failed to produce generalization to the three probe settings. Generalization training, which consisted of viewing videotapes of models who purchased items in the probe settings and answering questions about the models'' responses, was then introduced. Training with the videotapes resulted in generalization to the three community stores. Results of the use of videotapes as a cost-effective means to program generalization in community training programs are discussed.     

Shaping data collection congruent with experimental hypotheses

The influence of instructions and feedback from an experimenter on observational recordings of disruptive behavior was evaluated. Four subject-observers recorded four categories of disruptive behavior from videotapes of children in a classroom setting. Two sets of videotapes, labelled "baseline" and "treatment", were matched for rates of disruptive behavior in each category. The observers were told that two target behaviors were expected to decrease and the other two control behaviors were not expected to change during the treatment condition. During observational recording of treatment videotapes, the observers were given positive feedback when they reported decreases in the two target behaviors, and negative feedback when they reported either to change or increases in the two control behaviors. The target behaviors were recorded less frequently by observers, while recordings of control behaviors were unaffected during the treatment phase. These results suggest that contingent feedback to observers should be avoided as a possible source of bias in behavioral recordings.     

Integrating speech information across talkers,gender, and sensory modality: Female faces and male voices in the McGurk effect

Studies of the McGurk effect have shown that when discrepant phonetic information is delivered to the auditory and visual modalities, the information is combined into a new percept not originally presented to either modality. In typical experiments, the auditory and visual speech signals are generated by the same talker. The present experiment examined whether a discrepancy in the gender of the talker between the auditory and visual signals would influence the magnitude of the McGurk effect. A male talker’s voice was dubbed onto a videotape containing a female talker’s face, and vice versa. The gender-incongruent videotapes were compared with gender-congruent videotapes, in which a male talker’s voice was dubbed onto a male face and a female talker’s voice was dubbed onto a female face. Even though there was a clear incompatibility in talker characteristics between the auditory and visual signals on the incongruent videotapes, the resulting magnitude of the McGurk effectwas not significantly different for the incongruent as opposed to the congruent videotapes. The results indicate that the mechanism for integrating speech information from the auditory and the visual modalities is not disrupted by a gender incompatibility even when it is perceptually apparent. The findings are compatible with the theoretical notion that information about voice characteristics of the talker is extracted and used to normalize the speech signal at an early stage of phonetic processing, prior to the integration of the auditory and the visual information.

THE EFFECTS OF COMMUNICATION APPREHENSION ON COMMUNICATION EFFECTIVENESS1

This study investigated the following hypothesis: physiological, psychological, and verbal behavior indices of communication apprehension can predict comprehension, perception of speaker credibility, and ratings of speech effectiveness. The stimulus materials were videotapes of the first minute of 85 different students expressing their views on women's liberation. Measurement on all the indices of communication apprehension had been taken on these students as the videotapes were being prepared. Each of these one-minute videotapes was shown to a single receiver who then filled out forms measuring comprehension, perception of source credibility, and rating of speech effectiveness. Results supported the hypothesis that the indices of communication apprehension could predict all the communication effects save one, perception of character. The strongest relationship between the set of communication apprehension variables and the set of communication effectiveness variables indicated that individuals who reported high apprehension experienced much silence in their speech and received low ratings on language facility, vocal characteristics, and general effectiveness.     

Psychologists'' and teachers'' reactions to mental health and behavioral school consultation

School psychologists and elementary school teachers were shown videotapes of a psychologist consulting with a teacher, with the psychologist using either behavioral or mental health consultation techniques. Problem situations and teacher-consultee verbalizations did not differ across the two sets of videotapes. Afterwards, subjects judged the effectiveness of of the consultation and the personal attributes of the consulting parties. In general, teachers preferred behavioral consultation, while psychologists rated the mental health consultation as more effective. Implications of these findings for consultation reaearch and practice are discussed.     

Observational conditioning of fear to fear-relevant versus fear-irrelevant stimuli in rhesus monkeys

Two experiments examined whether superior observational conditioning of fear occurs in observer rhesus monkeys that watch model monkeys exhibit an intense fear of fear-relevant, as compared with fear-irrelevant, stimuli. In both experiments, videotapes of model monkeys behaving fearfully were spliced so that it appeared that the models were reacting fearfully either to fear-relevant stimuli (toy snakes or a toy crocodile), or to fear-irrelevant stimuli (flowers or a toy rabbit). Observer groups watched one of four kinds of videotapes for 12 sessions. Results indicated that observers acquired a fear of fear-relevant stimuli (toy snakes and toy crocodile), but not of fear-irrelevant stimuli (flowers and toy rabbit). Implications of the present results for the preparedness theory of phobias are discussed.     

Improving condom use intentions and behavior by changing perceived partner norms: an evaluation of condom promotion videos for college students.

OBJECTIVE: To examine the effectiveness of 2 condom promotion videotapes on self-efficacy, intentions, and behavior. DESIGN: Two hundred twenty college students completed social-cognitive and behavioral measures and were then randomly assigned to receive one of two 30-min condom promotion videotapes (male or female student presenters) or to a wait-list control condition. Participants who watched 1 of the videotapes completed immediate posttest measures, and 85% of participants completed a 4-month follow-up. MAIN OUTCOME MEASURES: Self-efficacy for condom use, intentions to use condoms, use of condom during last sex, and consistent condom use over the last month. RESULTS: Participants who received either video reported greater self-efficacy to refuse to have unprotected sex and intentions than controls at follow-up. Individuals who received either video were more likely than controls to report using a condom during last sex with a regular partner, and those who watched the female presenter were more likely to report consistent condom use. CONCLUSION: Participants benefited in terms of self-efficacy and intentions from receiving either video, but both men and women benefited more in terms of condom use behavior from receiving the female video. Future research is needed to determine whether opposite-sex speaker videos could be beneficial with a larger (and more sexually active) sample and whether these effects are maintained over time.     

How the quality of third parties' settlement solutions is affected by the relationship between negotiators

Observers watched videotapes of people negotiating. In half of the videotapes, the negotiators had a negative relationship; in the other half, the negotiators had a positive relationship. Some observers believed that the relationship was a genuine reflection of how the parties felt about one another; others were told that the behavior of negotiators was strategic (i.e., used by parties to gain advantage). Following the tape, observers recommended a settlement. Observers' suggestions were most efficient when the negotiators' relationship was positive and genuine; observers proposed significantly worse solutions when negotiators' relationships were negative and genuine. The authors advise mediators to focus on the issues rather than the emotional tone and to avoid the correspondence bias when observing conflicts among parties with negative relationships.     

Multiple audience problem: a strategic communication perspective on social perception

Examined how communicators send mixed messages containing an explicit surface content and a covert hidden content. In Study 1, Ss wrote constrained essays presenting either an introverted or extraverted personality. Although authors reported manipulating essay credibility and readers reported relying on credibility to make their judgments, readers succumbed to correspondence bias. In Studies 2 and 3, Ss again prepared either constrained essays (Study 2) or constrained videotapes (Study 3) and included in them a hidden message that would be understood by only their friends but not by strangers. Observers then read these essays or watched these videotapes. Friends detected and decoded the hidden messages, whereas strangers did not. We discuss these findings in terms of social perception and strategic communication.     

Participant Perceptions of Potential Employers

This study was designed to examine participants' perceptions of targets who varied in Likelihood to Sexually Harass (LSH; J. B. Pryor, 1987) scores. Ninety-four Caucasian participants were shown videotapes of male targets who had scored either high or low on the LSH scale. In half of the sessions, the participants watched the videotapes without sound and in the other half the participants watched the videotapes with the sound on. Participants then generated open-ended responses to a question asking them to imagine what it would be like to have this man as an employer. Judges who were unaware of the purpose of the study independently rated the open-ended responses for their evaluative implications (positive or negative), context (professional or interpersonal), as well as their domain (affiliative or dominant). Results indicate that overall men who were high in LSH were viewed most negatively and least positively compared to their low LSH counterparts. This is consistent with previous research by D. M. Driscoll, J. R. Kelly, and W. L. Henderson (1998) on identification of men with sexual harassment proclivity. Men who are high or low in LSH behave in different ways and participants are able to pick up on the cues associated with this important personality factor.     

In the Eye of the Beholder: Do Behavior and Character Affect Victim and Perpetrator Responsibility for Acquaintance Rape?1

Acquaintance rape attributions of responsibility were investigated. In Study 1, participants viewed videotapes that varied the female victim's resistance (verbal, physical, verbal/physical) and the reaction of the perpetrator (anger, no reaction) or a control videotape. The victim was held less responsible and the perpetrator was held more responsible when the victim resisted. In Study 2, participants viewed videotapes that manipulated victim and perpetrator reputation. Victims were held more responsible when they had a bad reputation; perpetrators were held more responsible when the victim had a good reputation or the perpetrator had a bad reputation. Hostile sexism predicted victim responsibility in both studies; rape myth predicted victim and perpetrator responsibility in Study 2. Implications for the legal system are discussed.     

Selective associations in the observational conditioning of fear in rhesus monkeys

Three experiments explored the issue of selective associations in the observational conditioning of fear. Experiment 1 results indicated that observer rhesus monkeys acquired a fear of snakes through watching videotapes of model monkeys behaving fearfully with snakes. In Experiment 2, observers watched edited videotapes that showed models reacting either fearfully to toy snakes and nonfearfully to artificial flowers (SN+/FL-) or vice versa (FL+/SN-). SN+/FL- observers acquired a fear of snakes but not of flowers; FL+/SN- observers did not acquire a fear of either stimulus. In Experiment 3, monkeys solved complex appetitive discriminative (PAN) problems at comparable rates regardless of whether the discriminative stimuli were the videotaped snake or the flower stimuli used in Experiment 2. Thus, monkeys appear to selectively associate snakes with fear.     

Body Language of Women and Judgments of Vulnerability to Sexual Assault

The present study experimentally examined the effects of body language on judgments of vulnerability to sexual assault by strangers. Four features of body language (stride length, weight shift, body-limb movement, and foot movement) were manipulated to create 2 typical victim profiles and 1 typical nonvictim profile. Short videotapes of 3 adult female models walking alone in each of the 3 body language profiles were filmed. Forty-one college students and 33 police officers individually viewed 3 videotapes (each showing a different model and a different body language profile) and made judgments for each about the woman's confidence level and vulnerability to sexual assault. As predicted, women in the 2 victim profiles were judged to be significantly more vulnerable to sexual assault and significantly less confident than women in the nonvictim profile. Implications and suggestions for future research are discussed.     

Fluency and eye contact as factors influencing observers' perceptions of stutterers

The purpose of this study was to determine the effects of different levels of eye contact and fluency on observers' perceptions of a speaker. One of four videotapes depicting an actor (playing the part of a supervisor) interviewing another actor (who played a subordinate) were shown to 127 college students. The four videotapes represented four different conditions comprising combinations of fluent vs nonfluent speech and normal vs low eye contact. Results indicated that these combinations of fluency and eye contact differentially influence listeners' perceptions of a speaker. Highest ratings were obtained for the fluent-normal eye-contact speaker, with lower ratings for all other conditions. In addition, it was determined that the frequency of eye contact rather than fluency was more strongly related to listeners' perceptions. The clinical implications of these findings are discussed.     

Biggest Isn't Always Best: The Effect of Breast Size on Perceptions of Women1

Research has demonstrated preferences for medium and large breasts and a tendency to associate positive attributes with larger breasts. Findings have been limited, however, by use of stimuli that do not depict women realistically or in a credible context. In the current study, a female actor's breast size was manipulated to create four videotapes (bra cup sizes A, B, C, and D) in which she delivered a speech. Participants viewed one of the four videotapes and rated the actor on social and professional characteristics. Males perceived the actor more favorably on both professional and social characteristics when she had a medium breast size, whereas females were generally not influenced by breast size. Findings are related to the popularity of methods to enhance breast size and the need for awareness of the potential impact of breast size on how women are perceived.     

Effects of chronic unemployment and acute psychological stress on sexual arousal in men

Effects on sexual arousal of unemployment and acute stress were studied in men. Ten unemployed (high-chronic-stress) and 9 employed (low-chronic-stress) men were exposed to two erotic videotapes in the laboratory. Acute stress was induced by telling the men that they would have to give a talk on their own sexual behavior and fantasies. Half the men were told about the talk before seeing either erotic tape, the other half were told in between the two erotic tapes. Cardiovascular measures confirmed the stressful nature of this manipulation. Results showed that the unemployed men achieved less penile tumescence than the employed men when stressed prior to erotic stimulation. Presentation of the stressor between the erotic videotapes (after sexual arousal occurred) produced no differences between the employed and unemployed men. These results suggest that impairment of erection occurs as a result of a combination of chronic and acute stress.     

EFFECTS OF A VIDEOTAPE FEEDBACK PACKAGE ON THE PEER INTERACTIONS OF CHILDREN WITH SERIOUS BEHAVIORAL AND EMOTIONAL CHALLENGES

Peer interactions are among the greatest challenges experienced by children who have severe emotional and behavioral problems. This study evaluated an intervention package designed to increase the ratio of these children's desirable to undesirable interactions. The package included three principal components: (a) observation of videotapes following regularly scheduled peer activity sessions; (b) self-evaluation of the children's peer interactions observed on the videotapes; and (c) delayed feedback and reinforcement for desirable peer interactions. Five students from two elementary schools participated. Multiple baseline designs and one reversal were used to evaluate the effects of the intervention package. The results showed that the intervention produced lower levels of undesirable peer interactions and higher ratios of desirable to undesirable interactions for all participants. The results are discussed in regard to their conceptual and applied implications and in terms of specific directions for future research.     

Children's perceptions of male and female principals and teachers

This study examined the influence of male and female school principals on first graders' perceptions of school principals and teachers. Participants were 190 male and female first graders who were shown four videotapes depicting all combinations of male and female teachers and principals. Results showed that children were accurate in their labeling of the videotapes regardless of whether the roles presented were stereotypical or counterstereotypical, and regardless of the sex of their principal. On rating scales, children with female principals were more nonstereotypical than children with male principals. Maternal employment was unrelated to their perceptions of teachers and principals. The results suggest that first-grade children do not hold overly stereotypic views and that the presence of both sexes as models for the role of school principal can have a noticeable positive effect on children's perceptions.
