The costs and benefits of processing emotional stimuli during rapid serial visual presentation

Using a dual-target identification task during rapid serial visual presentation (RSVP), we examined facilitation and interference effects exerted by emotional stimuli. Emotionally arousing first targets (T1s) were encoded with higher accuracy than neutral T1s. At the same time, identification of a second neutral target (T2) was impaired reflecting a failure of disengaging attention from arousing T1s. Similar interference was triggered by arousing filler stimuli that were not voluntarily searched for in the RSVP stream (Experiment 2). In Experiment 3, we showed that interference is reduced (though facilitation for arousing T1s is maintained) when the second task itself involves variations in emotional arousal. Vice versa, when arousal associated with the T2 stimulus was predictable, interference recurred (Experiment 4). Our findings indicate that the perceived emotional intensity of a stimulus is a determinant of successful identification during RSVP: Encoding of arousing stimuli is reliably facilitated. Interference effects with subsequent processing arise independently and are strongly modulated by the overall task context and specific processing strategies.     

Operant control of eye movements

In a monitoring situation eye movements were required in order for signals to be presented. Detection of signals was the reinforcement. A multiple schedule of fixed-interval reinforcement, differential reinforcement of low rate, and fixed-ratio reinforcement was established for eye movements. Results demonstrated that an eye movement can act as an operant controlled by its consequences. Operant control of eye movements has important implications for human factor analysts concerned with "attention".     

Selection,Function, and Assessment of Residence Hall Counselors

Two studies are reported which are concerned with the program of counseling in the women's residence halls of the University of Illinois. The first study demonstrated the inadequacy of the MMPI as a selection instrument for graduate assistants (G.A.'s) serving as residence hall counselors. The second study demonstrated: that students, G.A.'s, head residents, deans, and professional psychologists differ significantly in their definition of the G.A.'s function; that they differ less in defining the attributes of an ideal G.A.; that head residents and students do not differ significantly in their rating of a real G.A.; that the less experienced and the less able students ask more of a G.A. and value her more highly; that the program is functioning well as judged by student endorsement; and that neither the Strong, the Edwards, nor the CPI discriminate between the better and poorer G.A.'s. The data also suggest caution in generalizing results from one institution to another.     

Between- and within-person level motivational precursors associated with career exploration

Career exploration is a critical process for child and adolescent development leading people toward suitable work and developing a vocational identity. The present study examined the role of motivational precursors, namely work valences and personal agency beliefs, in explaining in-breadth and in-depth career exploration. Given the dynamic nature of motivation, we teased apart the between-person differences and within-person variabilities in motivational precursors to examine how they are independently associated with career exploration. Two hundred one high school students comprised the sample and were surveyed three consecutive years. Results revealed that work valences and agency beliefs were associated with career exploration at both the between- and within-person level. Further, when individuals exhibited greater level of agency beliefs and positive valences, they were more likely to exhibit more in-depth exploration one year later. Implications for career guidance are discussed.     

Latent profiles of work motivation in adolescents in relation to work expectations,goal engagement,and changes in work experiences

Motivation plays a key role in successful entry into working life. Based on a cross-sectional and a one-year longitudinal study, we used a person-centered approach to explore work-related motivation (i.e., autonomous goals, positive affect, and occupational self-efficacy) among 577 students in 8th grade (Study 1) and 949 adolescents in vocational training (Study 2). Based on latent profile analysis, in both studies we identified four groups that were characterized by different levels of overall motivation and one group characterized by low positive affect and mean levels in autonomous goals and self-efficacy. Profiles characterized by high levels of motivation showed the highest levels of positive work expectations and goal engagement and the lowest levels of negative work expectations in Study 1 and the highest levels of person-job fit, work engagement, and job satisfaction in Study 2. Moreover, latent difference score analysis showed that motivational profiles predicted changes in person-job fit and work engagement across one year but not in job satisfaction. The results imply that career counselors should be aware of characteristic motivational patterns of clients that may require specific counseling approaches.
