Response conflict theory,error rates and hybrid processing: A reply to McLeod

McLeod (1977) has proposed a parallel processing model of the psychological refractory period quite similar to an earlier model most recently adumbrated by Kantowitz (1974a). This article corrects some erroneous statements made by McLeod about the testability of the response conflict model and emphasizes the importance of error data in distinguishing among conceptually similar models of the PRP effect.     

Development of mental rotation: A speed-accuracy study

Pairs of letters and numbers were shown to 11-, 14-, and 19-year-olds. One stimulus in a pair was presented upright. The second, which was either identical to the first or a mirror image of it, was rotated 0 to 150° from the vertical. Individuals judged if the stimuli in a pair would be identical or mirror images if presented at the same orientation. They did so under instructions that emphasized accurate responses, fast responses, or fast and accurate responses. Typically, responses were (1) most accurate and slowest when accuracy was emphasized, and (2) least accurate but fastest when speed was emphasized. The data from the three instructional conditions were used to derive measures of response times in which accuracy of response was equated for the three age groups. At 95% accuracy 14- and 19-year-olds mentally rotated stimuli at the same rate, which was faster than 11-year-olds' rate. At 100% accuracy, 19-year-olds mentally rotated stimuli more rapidly than both 11- and 14-year-olds, who did not differ from one another.     

When is an easy task difficult and vice versa? A reply to lane

Lane has argued that kantowitz and Knight incorrectly predicted an interaction between primary and secondary task difficulty for the variable-allocation model of attention. It is shown that such an interaction is indeed obtained if task-performance difficulty is defined in terms of capacity and only reasonable transformations of data are permitted. This interaction holds for any set of monotonic resource operating characteristics.     

The effects of prior task experience in the modeling situation

An investigation was made into the effects of observers' previous experience with the experimental task on acquisition and subsequent performance of modeled task behavior. The task was socially neutral and the subjects were second grade boys and girls. Recall of modeled actions increased with prior experience, indicating greater acquisition. This finding supports Bandura's (1973) assertion that task familiarity may enhance attentiveness to the model. Contrary to previous research, performance of imitation did not decrease with experience. The present performance results are possibly due to the ambiguity of the preexperience and novelty of the experimental task.     

Perception of internal elements of compound figures by one-month-old infants

Previous research has shown that infants younger than 2 months frequently concentrate their attention on peripheral or external features of visual stimuli and that they do not appear to process the internal elements of a compound visual stimulus composed of a simple geometric figure enclosed in a larger figure. A visual habituation-dishabituation paradigm was used to determine whether 1-month-old infants would process internal information if the internal elements of the stimulus were patterns often found to be preferred by young infants. Four groups of eight infants each were habituated to a compound stimulus consisting of a square or triangle surrounding a checkerboard or bull's-eye. Following habituation each group was presented with one of four types of stimulus: the identical stimulus (control group), a stimulus differing only in the internal component, a stimulus differing only in the external component, or a stimulus differing in both components. The results of the present study suggest that when the internal element of a compound stimulus is a highly preferred or salient stimulus, the young infant will process information about its characteristics.     

Attributions and other inferences: Processing information about the self versus others

This study focuses on the attributional inferences involved in the comprehension of behaviors and on possible differences between the process of comprehending one's own behaviors and those of another person. Both the content of attributional judgments and the time taken to make the judgments were measured, in a design involving the comprehension of behaviors that were high or low in desirability and distinctiveness and that were understood as the subject's own versus another person's. Results show that the inferential processes in the comprehension of one's own and another's behavior are generally similar. Exceptions are where organized knowledge about the self (a self-schema) is brought into use and where differences in “perspective” between self and other influence processing. Discussion centers on the implications of the results for theories of comprehension and inference, including extensions needed to handle the self/other distinction.     

Social skills training and systematic desensitization in reducing dating anxiety.

Cooper et al. (1969) have criticized the types of target behavior chosen for therapy analogue studies for being irrelevant to clinical practice. A potential target behavior which appears to be pervasive, complex and directly relevant to clinical practice is interpersonal anxiety. Of special concern to college students is the interpersonal anxiety elicited by members of the opposite sex. especially in dating situations (Martinson and Zerface, 1970).An individual may experience interpersonal anxiety because of a deficit in social skills (reactive anxiety) or because of prior conditioning (conditioned anxiety) or because of some combination of both reactive and conditioned components. While it is possible that a treatment program aimed at a reduction of either of these anxiety components may be instrumental in ameliorating the other component, it would appear that a comprehensive treatment program would attempt to teach social skills as well as reduce conditioned anxiety.Desensitization procedures have demonstrated success in alleviating conditioned anxiety for a wide variety of clinical problems (Paul, 1969a. 1969b) and appears to be a logical choice for the conditioned component of dating anxiety. A number of outcome studies have reported some success in the use of in vivo desensitization (Rehm and Marston, 1968; Martinson and Zerface, 1970) and systematic desensitization (Stark, 1970) in reducing anxiety in date anxious subjects.The literature on treatment programs aimed at social skills training for date anxious subjects is meager. Melnick (1973) reported success in improving the appropriateness of the social behavior of subjects who had experienced a minimal dating history by the use of modeling, behavioral rehearsal and self-observation techniques.The present study was designed to test the relative effectiveness of two different types of treatment programs in alleviating interpersonal dating anxiety. The two experimental groups consisted of a systematic densensitization program which focused on the condition anxiety component and a social skills training program which focused on the reactive anxiety component.     

Clogs in the bogus pipeline: Demand characteristics and social desirability

Jones and Sigall (1971) have advocated the use of a pseudophysiological monitoring device (the bogus pipeline) as a procedure to measure the “true” feelings of experimental subjects. A comparison of the bogus pipeline and a paper-and-pencil scale as measures of attraction indicated that the monitoring device is affected by experimenter demands among high social desirability (SD) subjects (p < .03) while the simple rating scale is not. Attraction to a stranger was determined solely by attitude similarity for high SD subjects using the paper-and-pencil measure and for low SD subjects in both measurement conditions. Use of the bogus pipeline in the typical attraction experiment thus would seem to be contraindicated. These results were discussed with respect to Ostrom's (1973) criteria of relative sensitivity and functional comparability of measurement techniques.     

Heightened sexual arousal and physical aggression: An extension to females

In order to examine the effects of heightened sexual arousal upon aggression by females, subjects were first angered or not angered by a female confederate, next exposed to one of four types of stimuli (nonerotic scenes; pictures of seminude young males; pictures of nude males; pictures of couples engaged in various acts of lovemaking), and finally provided with an opportunity to aggress against the confederate by means of electric shock. In accordance with previous research conduced with males, it was hypothesized that exposure to mild erotic stimuli would inhibit subsequent aggression, while exposure to more arousing stimuli of this type would facilitate such behavior. Results offered support for both predictions. In addition, it was found that females responded with increased aggression to types of erotic stimuli previously found to inhibit such behavior by males.     

Atttudes and behavior: Implications of attitudes toward behavioral alternatives

The relationship between attitudes and behavior was considered. An attitudinal model of behavioral alternatives was presented and its applied and theoretical implications explicated. Three investigations were reported that tested the initial viability of the approach. Support for the model was observed in all three investigations.     

Algorithms for processing spatial information

Pairs of stimuli taken from a psychometric measure of spatial aptitude were shown to 9-year-olds, 13-year-olds, and adults. The stimuli in pairs were (a) either identical or mirror images, and (b) presented in orientations that differed by 0-150 degrees. Individuals judged, as rapidly as possible, if the stimuli in a pair would be identical or mirror images if presented at the same orientation. In Experiment 1, in which the stimuli were letter-like characters, at all ages most persons solved the problems using an algorithm in which an individual encodes the stimuli in working memory, mentally rotates one stimulus to the orientation of the other, compares them to determine if they are identical, and responds. In Experiment 2, the stimuli were multielement flags; here, the modal algorithm for both 9- and 13-year-olds differed from the previously described algorithm in that if the comparison process revealed that the stimuli were dissimilar, individuals did not respond immediately, but continued processing until a self-imposed deadline was reached. Among adults, the modal algorithm was the same one used in Experiment 1. Results are discussed in terms of the roles of encoding in contributing to the use of a particular algorithm.     

Attraction and altruism: With a little help from my friends

The present experiment was designed to determine whether the reinforcement value of an altruistic response is a function of attraction toward the victim and/or the affective state of the subject. Subjects (N = 95) received positive or negative evaluations from a victim or from a bystander and subsequently performed an altruistic response which terminated shock delivery to a victim on a series of 14 trials. Analyses of variance indicated that the acquisition of an altruistic response was greatest when attraction toward the victim was most positive (p < .0001) and nonexistent when attraction toward the victim was least positive. The results were consistent with the proposition that attraction rather than affect mediates altruistic reinforcement. Those subjects receiving negative evaluations from the victim failed to acquire the altruistic response, suggesting that failure to help may function as a form of passive aggression.     

A Plumber's friend in need is a Plumber's friend indeed

In response to the critique of Gaes, Quigley-Fernandez, and Tedeschi (Journal of Research in Personality, 1978, 12, 189–192) it was acknowledged that the cell Ns were incorrect as originally reported, and the weakness of a postexperimental division of subjects was reaffirmed. Emphasis was placed on the comparability of a simple rating scale and an elaborate bogus pipeline in measuring attraction. The need for determining the way in which the bogus pipeline functions prior to its uncritical adoption in any given experimental situation was stressed as a point of agreement.     

Situation-specific variables as determinants of perceived environmental aesthetic quality and perceived crowdedness

It was hypothesized that relevant situation-specific variables may act along with objective physical conditions to determine environmental perception, and that the exclusive use of the physical level of an environmental stimulus to predict behavior may, therefore, be inadequate. A 2 × 4 between-subjects design was employed in which an attitudinally similar or dissimilar confederate interacted with a subject at one of four distances. As hypothesized, subjects who interacted with a similar confederate judged the environment to be of higher aesthetic quality, perceived themselves to be less crowded, and felt affectively more positive than subjects who interacted with a dissimilar other. The results were also interpreted as supporting the utility of the Byrne-Clore (1970) reinforcementaffect model of evaluative responses as a means of predicting environmental perception and the behavioral response to environmental stimuli.     

Channels and stages in human information processing: A limited analysis of theory and methodology

This article reviews the status of the theoretical construct of capacity. Four basic questions are discussed: (1) What is capacity? (2) How is capacity measured? (3) Is capacity limited? (4) If so, where is it limited? It is claimed that empirical answers to these questions have been unsatisfactory due to theoretical and methodological issues that need be resolved. Data are presented to illustrate such difficulties. The construct of capacity has become more and more vacuous and caution is required whenever capacity is invoked to explain behavior. These problems can be overcome by careful research and well-defined models. Capacity can be a soup stone, a millstone, or a touchstone, depending upon how it is used.     

Problems with a false recognition paradigm for developmental memory research

Developmental changes in memory organization based on synonym and antonym relationships were examined in three experiments. Although Cramer (1973) claimed that second-grade children organized their memory for words based on synonym relationships while sixth-graders used antonyms, no support for this interaction was found. The present studies employed additional procedures in an attempt to replicate and extend Cramer's finding. Some inadequacies of a false recognition paradigm for developmental research are identified and some alternative analyses are proposed.     

Threatened retaliation from the victim as an inhibitor of physical aggression

Sixty male undergraduates participated in an experiment designed to investigate the effects of apparent probability of retaliation from the victim and level of prior anger arousal upon adult aggressive behavior. It was hypothesized that threatened retaliation would be highly effective in inhibiting subsequent aggression under conditions where subjects had not previously been angered by the victim, but would generally fail to inhibit such behavior under conditions where they had previously suffered strong provocation at the hands of this person. Support was obtained for both of these predictions. Findings were discussed in terms of their implications for the prevention and control of human violence in naturalistic social situations.
