Changes in subject performance during the semester: An empirical investigation

Two experiments were conducted to probe for performance differences between early-semester subjects and late-semester subjects in an introductory psychology subject pool. In Experiment 1A, hypotheses regarding changes in performance included differential effort, changes in subjects’ attention to the task, and changes in subjects’ sensitivity. A signal detection paradigm was used, and 278 subjects were sampled over the course of the semester. No evidence of changes in subject performance was found, in spite of sufficient power to detect relevant patterns of change. The results of a replication (N = 135) were consistent with those of Experiment 1A. Experiment 2 (N = 118) employed a text comprehension task to examine possible differences in subject performance with a more cognitive task. Again, there was no evidence to support the idea that late-semester subjects were performing differently from early-semester subjects.     

Early predictors of career development: A 10-year follow-up study

This paper presents empirical findings from a 10-year longitudinal study of the educational and occupational socialization of 445 participants who were about 7 years old when first tested, and about 17 years old at the fourth time of measurement. In addition to collecting psychological measurements from the participants, behavioral reports were collected from significant others, specifically parents and teachers. Findings demonstrated that the life/career evolution of the participants can be understood only when taking into account the dynamic interaction between the unique personal characteristics of individuality of each person and the psychosocial theatre within which the person’s development takes place. Using the life-span, life-space framework of Super, and the Developmental-Contextual model from Vondracek, different emerging early predictors with unique impact on the process of educational and occupational socialization were identified, especially with respect to the probability of dropping out of school. Results in terms of gender, parental influences, psychological characteristics, and social context are discussed with regard to their potential implications for psychological interventions in schools, families, and occupational settings, as well as with regard to personal counseling in what concerns the management of life circumstances and behavioral ecosystems.     

Extraversion,Neuroticism, and Face-Name Learning

Previous research has attempted to relate personality traits to paired-associate learning. We tested name recall as a function of extraversion and neuroticism (as assessed by the Eysenck Personality Inventory) and task difficulty. Face photographs were paired with one of three levels of information: names only (an easy task); names and occupations; or names, occupations, and interests (a difficult task). On the easy and difficult tasks, extraverted subjects recalled more names than did subjects scoring at the median or below on that trait. Contrary to expectations, subjects scoring high on neuroticism recalled more names than did subjects scoring low on that trait. Neither trait was significantly related to recall on the moderately difficult task. There was no interaction between traits for name recall, but there was for interests: Neurotic introverts were significantly impaired at recalling interests, whereas the other subjects recalled interests better than names. These findings thus differ from those of paired-associate learning tasks using words and nonsense syllables.     

Individual behavior in learning of an artificial grammar

Artificial grammar learning (AGL) is a widely used experimental paradigm that investigates how syntactic structures are processed. After a familiarization phase, participants have to distinguish strings consistent with a set of grammatical rules from strings that violate these rules. Many experiments report performance solely at a group level and as the total number of correct judgments. This report describes a systematic approach for investigating individual performance and a range of different behaviors. Participants were exposed to strings of the nonfinite grammar A ⁿ B ⁿ . To distinguish grammatical from ungrammatical strings, participants had to pay attention to local dependencies while comparing the number of stimuli from each class. Individual participants showed substantially different behavioral patterns despite exposure to the same stimuli. The results were replicated across auditory and visual sensory modalities. It is suggested that an analysis that looks at individual differences grants new insights into the processes involved in AGL. It also provides a solid basis from which to investigate sequence-processing abilities in special populations, such as patients with neurological lesions.     

Idols and Demons: On Discerning the Spirits

This article elaborates on the distinction between two spiritual ailments, which can be properly identified as idolatry and demonry. They represent opposite but complementary age–long phenomena still relevant to the analysis of the contemporary spiritual situation in explaining disorders of the soul as well as cultural derangement. The text suggests that the church as the spiritual community is the locus for the discernment of the spirit and that in its two distinguishing foundational and functional features (the proclamatory function and the communion function) it is molded precisely to confront both idols and demons.     

Effect of positive,negative, and mixed occupational information on cognitive and affective complexity

A series of concentrated research studies over the past 8 years has significantly demonstrated that cognitive complexity in the vocational realm is positively related to congruence or appropriateness of vocational choice. Moreover, research has shown that introducing occupational information significantly reduces, rather than increases, cognitive complexity. The results of the study reported here relate to changes in cognitive complexity as a function of the type of occupational information introduced, namely, information with respect to the advantages of occupations; the disadvantages of occupations, or a combination of positive and negative features of occupations. Our results clearly demonstrated that while positive occupational information alone leads to greater simplicity, negative or mixed information significantly retards the trend toward greater simplicity. Results are discussed from both theoretical and practical perspectives, especially with reference to the typical occupational information provided in routine vocational counseling.     

Unconscious perception or not? An evaluation of detection and discrimination as indicators of awareness

Most investigations of unconscious perception use a dissociation design in which an awareness variable (e.g., detection) is compared with a perceptual processing variable (e.g., identification). Unconscious perception is inferred when the awareness variable lacks sensitivity to the stimulus but evidence of perceptual processing is still obtained. In two studies we examined the relationship between word identification and detection (Study 1) or discrimination (words vs. nonwords; Study 2) with a variety of techniques. In both studies, dissociations suggestive of unconscious perception occurred when the data were examined with subjective threshold approaches, but these differences disappeared when the variables were compared with techniques derived from signal detection theory (SDT). These results do not support unconscious perception in subjective threshold paradigms. In addition, detection appears to be the most sensitive and appropriate task for assessing stimulus awareness, provided that several SDT assumptions are met.     

Television and aggression: a test of a mediated model with a sample of Portuguese students

We examined the role of identification with violent TV heroes, enjoyment of TV violence, and perceived reality in TV violence as mediators of the relationship between viewing TV violence and subsequent physical and verbal aggression. A sample of 722 4th, 6th, and 8th grade students from schools in the central region of Portugal completed measures assessing enjoyment of TV violence, perceived reality, aggression, identification with violent TV heroes, and exposure to TV violence. The results showed that the relationship between TV violence and physical aggression is mediated by enjoyment of TV violence, perceived reality in TV violence, and identification with violent TV heroes. The TV violence to verbal aggression relationship was also mediated by enjoyment of TV violence.

Highly correlated stimuli do not necessarily facilitate the measurement of unconscious perception: Exclusion failure is hard to find in forced-choice tasks

Persaud and McLeod (2008) report that unconscious perception is easier to measure with forced-choice exclusion tasks when the stimuli are highly similar, such as choosing between the letters ‘h’ and ‘b’. The high degree of stimulus similarity may decrease conscious awareness of the target stimuli while leaving unconscious cognition intact. The present experiments used forced-choice exclusion tasks (i.e., choosing the opposite of a masked target stimulus) with the aim of replicating these findings. No evidence of relevant perception – either conscious or unconscious – was obtained with short duration targets. The forced-choice exclusion task was correctly performed at longer target durations (25 ms and higher), which suggests conscious perception of the target stimuli. We conclude that increasing stimulus similarity does not reliably produce exclusion failure effects and does not appear to facilitate the measurement of unconscious cognition.
