Care Orientation in the Teens as a Predictor of Young Adult Psychosocial Adjustment

The transition from adolescence to young adulthood is a watershed period in development that carries risk for poor psychosocial adjustment. It also carries potential for positive transitions into the caregiving roles and responsibilities of adult life. Research to date has predominantly focused on adolescent predictors of problematic rather than positive transitions; yet predictors of the latter hold equal (if not greater) promise for informing health promoting interventions. The purpose of this study was threefold: (1) to use Latent Profile Analysis (LPA) to define patterns of psychosocial adjustment and maladjustment in young adulthood (21-years of age); (2) to examine the unique role of adolescent prosocial behaviour (e.g., volunteering and civic engagement) in promoting adjustment and reducing maladjustment in young adulthood; and, (3) to examine whether protective developmental relationships are maintained after adjustment for other covariates including socio-economic background factors and personality characteristics. Data were drawn from the Victorian cohort of the International Youth Development Study (IYDS; N = 2407), a representative sample of students in Victoria, Australia. Students were assessed in Grade 9 (Mean age = 15-years) and followed up at age 21-years. LPA identified three psychosocial adjustment classes at age 21 defined as: (1) Adjusted (24.8 %); (2) Normative (63.9 %); and, (3) Maladjusted (11.3 %). Adolescent volunteering, belief in a moral order, family opportunities for prosocial behaviour, and commitment to school were associated with enhanced adjustment and reduced maladjustment in young adulthood. Findings highlight the potential benefit of interventions designed to enhance adolescent prosocial behaviours and care orientation in promoting healthy transitions into young adult life.     

Case-Mixing Effects on Spelling Recognition: The Importance of Test Format

In a multiple-choice spelling recognition test, 56 university students were more accurate on more regular than irregular words, and on lower-case than mixed-case words, with the case mixing effect greater for irregular than regular words. In Experiment 2, the same words were presented singly in correct or incorrect spellings and distortion of word shape was achieved by case mixing (32 subjects) or by alternating the size of lower-case letters within a word (32 subjects). The main effects of regularity and distortion were replicated and the effect of distortion was greater for incorrect than correct stimuli, with correctly spelled words suffering a decrement in accuracy of less than 5 percentage points. Case mixing had a greater effect than size mixing on response latencies. In Experiment 3, with comparable test procedures, case mixing interacted with regularity in the subjects analysis for the multiple choice format, but not the single presentation format. This result indicates that comparisons based on visual configuration may be an artifact of multiple-choice tests.     

The effects of student gender,race, and achievement on career exploration advice given by canadian preservice teachers

This study investigated the effects of gender, race, and achievement on ratings of appropriateness of occupations and classifications of occupations (people, data, things) suitable for future exploration by ninth-grade students. The subjects (N=125; 106 females, 19 males), advanced undergraduate education students, were each asked to evaluate a case folder in which gender (female, male, not stated), race (Native, non-Native), and achievement (higher average, lower average) were systematically varied. Subjects gave ratings of appropriateness for future exploration of occupations on 5-point Likert-type scales. The occupations rated also represented three classifications (data, people, things), yielding a second dependent variable. Analysis was accomplished using two four-way analyses of variance. The attribute most influencing ratings was achievement. However, the three-way interactions of gender, race, and achievement limit direct interpretation of the data, and suggest that complex combinations of student attributes influence teachers. The limitations of the present study are emphasized; the implications for advising young women and for future research are discussed.     

Irrational Beliefs and Behavioral Misregulation in the Role of Alcohol Abuse Among College Students

Two hundred three alcohol-using college students completed a questionnaire on their levels of alcohol use, moderate to severe problems with alcohol use, and measures of life stress, impulsivity, compulsivity, irrational beliefs, and depression. While impulsivity significantly predicted both alcohol use and problems, stress, compulsivity, irrational beliefs, and depression were found to only be significant predictors of alcohol use problems. When irrational beliefs, impulsivity, and compulsivity were combined to form an irrational coping scale, this construct was found in multiple regression analyses to completely mediate the effect of stress on alcohol use problems, while depression was a partial mediator of this effect. Results were interpreted in terms of Rational Emotive Behavior Theory.     

The effect of metronome pacing on selected aerodynamic patterns of stuttered speech: Some preliminary observations and interpretations

The purpose of this investigation was to provide some preliminary data regarding the effects of metronome pacing on physiological aspects of speech during stuttering. Five aerodynamic measures were chosen as dependent variables: (a) peak intraoral air pressure, (2) intraoral air pressure onset duration, (3) intraoral air pressure offset duration, (4) total intraoral air pressure duration, and (5) peak air flow rate. Five adult stutterers and five adult nonstutterers read a prose passage containing 12 English consonants, each in three syllable-initial stressed positions, during a control condition and experimental condition. In the experimental condition the subjects read the passage while synchronizing one word per beat at 60 beats per minute. The results demonstrated that both stutterers and normals evidenced lower peak pressures and greater pressure durations during metronome pacing. Air flow rates increased for normal subjects and decreased for stutterers in the experimental condition. Dysfluencies recorded during the control condition were observed to have much more rapid intraoral air pressure onsets when compared with fluent counterparts in the experimental reading. These results were interpreted with reference to Wingate's (1969) modified vocalization hypothesis and Van Riper's (1971) altered timing concept.     

Conditioning of the aggressive behavior of pigeons by a fixed-interval schedule of reinforcement

Operant reinforcement of aggression was studied in food-deprived pigeons by delivering food for attacks against a target pigeon. The food was delivered according to a fixed-interval schedule and attack behavior was recorded automatically. Attack could be conditioned and extinguished, and the proportion of time spent in attack was a direct function of the frequency of reinforcement of the attack. The fixed-interval schedule produced an increasing rate of attack during the interval between food reinforcements. This positive curvature was an inverse function of the duration of the interval. The findings revealed that the duration and temporal patterning of the complex social behavior of attack can be influenced in a substantial and predictable manner by the schedule and frequency of operant reinforcement.     

The opportunity for aggression as an operant reinforcer during aversive stimulation

Squirrel monkeys were provided with a chain-pulling response which produced an inanimate object that could be attacked. In the absence of pain-shock, little or no chain-pulling occurred. When pain-shocks were delivered, chain-pulling responses increased. The chain-pulling response was successively reinforced, extinguished, reinforced, and again extinguished by presenting or withdrawing the opportunity to attack as the reinforcing event. Aggression appears to be a distinctive motivational state which is produced by aversive stimulation and which can be used to condition and maintain new behavior.     

Students' perceptions of male sexually aggressive behavior as a function of educational level and gender

Two hundred and four students (108 college freshmen, sophomores, juniors, and seniors; 96 high school juniors and seniors) participated in this study. The socioeconomic status of the participants (high school = 93% Caucasian, 7% African-American; college = 96% Caucasian, 4% African-American) was primarily in the lower middle-class range. The purposes of this investigation were (1) to test whether or not differences exist between high school and college students' perceptions of one form of male sexually aggressive behavior against women, (2) to determine if differences exist between male and female students' perceptions of such behavior against women, and (3) to explore the sex role socialization theory by providing empirical observation of its basic tenets. Findings suggested that boys may experience slower maturation and development of sensitivity toward sexual aggression than girls, but that this gap may lessen with advancing age for college males.
