Learned resourcefulness, drinking, and smoking in young adults

The purpose of this study was to examine the relationship between learned resourcefulness and two common addictive behaviors, namely, drinking and smoking. Male and female college students (N = 175) completed the Self-Control Schedule (SCS), the Quantity-Frequency-Variability questionnaire, and a smoking history form. Learned resourcefulness was related to self-reported patterns of alcohol consumption; specifically, heavy drinking subjects were lower in learned resourcefulness than were light and moderate drinkers who, in turn, were lower in learned resourcefulness than were infrequent drinkers and abstainers. Learned resourcefulness was only modestly related to smoking, with students who had never smoked evidencing somewhat higher learned resourcefulness than ex-smokers and current smokers. Overall, these data provide correlational support for the notion that learned resourcefulness may protect young adults against substance abuse.     

A Rorschach investigation of narcissism and hysteria in antisocial personality

We investigated Rorschach responses associated with narcissism and hysteria in a group of antisocial personality disordered offenders. The Rorschach protocols of 42 subjects who met the criteria from the Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev. [DSM-III-R]; American Psychiatric Association, 1987) for antisocial personality disorder were analyzed using Exner's (1986) criteria for pairs, reflections, and personal responses, and Gacono's (1988) criteria for the impressionistic response. Severe, or primary psychopaths (n = 21), scoring greater than or equal to 30 on the Hare (1980) Psychopathy Checklist (PCL), were compared to moderate, or secondary pscyhopaths (n = 21), scoring less than 30 on the PCL. The mean number of pair and impressionistic responses did not significantly differ for the two antisocial groups. The highly psychopathic group, however, did exhibit a significantly greater mean number of reflection and personal responses. We discuss pair and reflection responses and their relationship to narcissism in psychopathic disturbance. We recommend interpreting the personal response within the context of the psychopathic character and view personal responses as expressions of narcissism and omnipotence in highly psychopathic subjects. We also hypothesize that the impressionistic responses are indicative of primitive dissociative processes and hysteria in psychopathic subjects, and that their presence provides construct validity for the work of Guze (1976) and others who suggested an underlying histrionic dimension to psychopathy.     

Four Systems Anxiety Questionnaire (FSAQ): a self-report measure of somatic, cognitive, behavioral, and feeling components

This article presents the development of a 60-item self-report known as the Four Systems Anxiety Questionnaire (FSAQ). The FSAQ assesses anxiety on four components: somatic, cognitive, behavioral, and feeling. The FSAQ was given to 218 first-year university students, 54 anxiety patients attending clinical psychology departments, and 14 agoraphobic patients pre- and postpsychological treatment. Results reveal satisfactory reliability and validity levels. In addition, we proved that the FSAQ is sensitive to change following psychological treatment.     

Psychological assessment of catatonic schizophrenia

Probably due to the rarity of the disorder and the general inability of catatonic patients to cooperate with standardized assessment, no data exist documenting the psychological features associated with catatonic schizophrenia that may appear on psychological tests. This study utilized standard assessment techniques to examine clinical hypotheses regarding the psychogenic correlates of catatonic conditions from the performance of one man on psychological tests. In accordance with previous theory, test findings indicated frequent constriction, rigidity, and negativism in conjunction with compulsive traits. Experiences of cognitive and self-fragmentation were juxtaposed with a formal, mechanistic body ego; disorganization and discontinuity were countered with attempts at self-cohesion. Depressed feelings and human interest were apparent, although interpersonal relatedness was frequently characterized by an avoidant, distancing style.     

Delayed and current stimulus control in successive discriminations

In a successive discrimination in which successively alternating red and green hues signaled component variable-interval schedules, sensitivity of the ratio of responses in the two components to variation in the component reinforcer ratio decreased systematically during the course of the component. This decrease in stimulus control or discrimination over the course of the component was shown to be the result of delayed control of responding during the component by the stimulus transition between components. When the red–green stimulus transition was altered by interpolating a white stimulus at the end of each 60-s component, discrimination at the beginning of the component (measured by the power-function exponent for sensitivity to reinforcement) was reduced. Conditions with the white stimulus inserted in other quarters of the component indicated that the current discriminative stimulus exerts control over responding throughout the component, whereas during about the first half of the component, response differentials are influenced by the transition between discriminative stimuli.     

Additional-delay schedules: A continuum of temporal contingencies by varying food delay

Pigeons performed on discrete-trial, temporally defined schedules in which the food delay (D) was adjusted according to the latency of the key peck (X) and two schedule parameters (t and A). The schedule function was D = A(t − X), where D is the experienced delay between a response and a reinforcer. The schedule parameter t is the maximum value below which the present contingencies occur. A is the additional delay to reinforcement for each second the response latency is shorter than the t value. When A = 0 s, the schedule is a continuous reinforcement schedule with immediate reinforcement. When A = 1 s, the schedule is a conjunctive fixed-ratio 1 fixed-time t-s schedule. When A approaches infinity, the schedule becomes a differential reinforcement of long latency schedule. The latencies for subjects with t = 10 s and t = 30 s were observed with the present schedules having seven values for A between 0 s and 11 s. In addition, the latencies for subjects for which t = 30 s were observed at an A value of 31 s to 41 s. As the A value increased, the latencies approached the t value for subjects for which t = 10 s. The latencies for 30-s-t subjects did not approach t, even when the A value was 41 s. The latencies for 10-s-t subjects at 11-s A value were longer than those under yoked conditions having exactly the same delays/interreinforcement intervals. These results demonstrated a continuum of latency related to the schedule continuum (value of A) at a small t value.     

Determinants of pigeons' waiting time: Effects of interreinforcement interval and food delay

Four pigeons performed on three types of schedules at short (i.e., 10, 30, or 60 s) interreinforcement intervals: (a) a delay-dependent schedule where interreinforcement interval was held constant (i.e., increases in waiting time decreased food delay), (b) an interreinforcement-interval-dependent schedule where food delay was held constant (i.e., increases in waiting time increased interreinforcement interval), and (c) a both-dependent schedule where increases in waiting time produced increases in interreinforcement interval but decreases in food delay. Waiting times were typically longer under the delay-dependent schedules than under the interreinforcement-interval-dependent schedules. Those under both-dependent schedules for 1 subject were intermediate between those under the other two schedule types, whereas for the other subjects waiting times under the both-dependent procedure were similar either to those under the delay-dependent schedule or to those under the interreinforcement-interval-dependent schedule, depending both on the subject and the interreinforcement interval. These results indicate that neither the interreinforcement interval nor food delay is the primary variable controlling waiting time, but rather that the two interact in a complex manner to determine waiting times.     

Negative priming in same-different matching: further evidence for a central locus of inhibition

Responses to recently ignored information may be slower or less accurate than responses to information not recently encountered. Such negative priming effects imply that the mechanism of selective attention operates on unattended, as well as attended, information. In the present experiment, subjects judged the second and fourth letters of five-letter strings (e.g., BABAB) as "same" or "different." Responses were slower when a target letter was identical to the distractors presented in the immediately preceding trial. This effect did not depend on which response was required on the current or preceding trial. The results suggest that ignored information is functionally disconnected from the response system as a whole, rather than from a specific response.     

Visual stimulus input, saccadic suppression, and detection of information from the postsaccade scene

Tachistoscopic presentation of saccadic stimulus sequences to fixating subjects produced saccadic suppression curves only when the pre- and postsaccade fixation fields were structured. Displacement in the sense either of movement of the intrasaccade display or of change from pre- to postsaccade fixation field was not required. Variation of intrasaccade displays from contours moving at saccadic rates to a stationary gray field had no effect. When one structured field immediately followed another, the change of sensitivity mimicked suppression, but an interposed grayout magnified the loss and therefore probably reduced carryover from the first fixation field. Interposed grayout also delayed recovery but reduced the latency of detection of information from the postfield, so that it appears to have reduced stimulus overload from the sudden presentation of the second field.
