Too Close to Quit: The Role of Project Completion in Maintaining Commitment1

Conlon and Garland (1993) demonstrated that information about the degree of project completion, as compared with information about sunk costs, seemed to be the driving force behind continued investment in an R&D project. In the present paper, we replicate and extend this work. In studies with experienced bank managers, Chinese graduate students, and advanced-level MBA students, we find overwhelming support for the importance of project completion on investment intentions, with no indication of typical sunk cost effects. We argue that our results support a goal substitution explanation for many escalation phenomena where, as progress moves forward on a project, completion of the project itself takes increasing precedence over other goals (e. g., economic profit) that may have been more salient at the time the project was initiated.     

A cognitive mediation theory of task goals and human performance

A theory is proposed to explain the linkages between individual task goals and performance. Two cognitive constructs are postulated to mediate between task goals and performance:performance expectancy and performance valence. It is asserted that an individual's task goal has a positive influence on performance expectancy and a negative influence on performance valence. Performance expectancy is proposed to have a positive influence on performance while performance valence is proposed to have a negative influence on performance. Task ability is hypothesized to influence performance both directly and indirectly through its influence on performance expectancy. A laboratory experiment was designed to test the causal model proposed by the theory. A path analysis on the data from this experiment provides strong support for the model, with performance expectancy, performance valence, and task ability predicting 63% of the variance in performance on the laboratory task.     

Cognitive advantage in sport: the nature of perceptual structures

To extend and clarify the nature of the perceptual processes used by sport experts to perceive schematic sport information, two experiments used schematic football diagrams that varied in structure (structured vs. unstructured) and complexity (complex vs. easy). The primary objective was to examine and characterize the nature of the perceptual structures (chunks) that are initially encoded, stored, and subsequently retrieved. In Experiment 1, compared with nonexperts, experts recalled larger perceptual structures following the initial stimulus presentation of structured stimuli only, replicating the recall findings of previous research in other skill domains. Experiment 2 used a long-term memory recognition task and a sorting task. Experts had superior recall and recognition of structured stimuli only, along with more discriminating sorting criteria of perceptual structures within long-term memory. This suggests that experts possess a highly refined semantic network or organized, structured schematic information. This research extends and clarifies the similarities between the perceptual processes of experts in sport (i.e., football) and experts in skill domains that require obvious cognitive involvement (i.e., chess). The results are discussed with reference to the perceptual and conceptual chunking hypotheses. It is proposed that sport experts' knowledge of a conceptual category enables them to retrieve elements using a "generate-and-test process."     

Exploring the effect of therapists' treatment practices on client attendance in community-based care for children

Sustained treatment attendance has been reported to be poor in publicly funded community-based clinic settings serving children and families. Several child and family characteristics have been shown to predict attendance in community-based care, but virtually no research has been conducted to examine how experiences in care, including psychotherapists' within-session practices, influence client attendance. The goal of this exploratory study was to examine how observed practice within sessions, in particular the extent to which therapists delivered elements consistent with evidence-based practices, impacts total number of sessions attended, while accounting for an array of other potential predictors. Participants include 181 children ages 4-13 and their parents entering a new episode of care for disruptive behavior problems in publicly funded clinics. Data sources include administrative billing records on treatment attendance; coded videotaped treatment sessions; and self-reports from children, parents, and therapists. Results indicate that parent education, service funding source, parent alliance with therapist, and therapist experience predicted number of sessions attended; intensity of evidence-based treatment techniques delivered to children was marginally associated with attendance (p = .059). Implications for improving engagement in community-based care are discussed.     

The ABCs of CBT (Cognitive Behavior Therapy): Evidence‐Based Approaches to Child Anxiety in Public School Settings

This study evaluated a locally developed cognitive behavior therapy (CBT) intervention program in a public elementary school. In the prevention approach, 118 children were randomly assigned either to an 8‐week intervention or to a waitlist control. Results of statistical analysis indicated that the manualized CBT intervention did not reduce symptoms of anxiety on either self‐reports or parent reports of anxiety symptoms in the general school population. Challenges to translational efforts to public school settings are discussed.     

Convention in joint activity

Conventional behaviors develop from practice for regularly occurring problems of coordination within a community of actors. Reusing and extending conventional methods for coordinating behavior is the task of everyday reasoning .
The computational model presented in the paper details the emergence of convention in circumstances where there is no ruling body of knowledge developed by prior generations of actors within the community to guide behavior. The framework we assume combines social theories of cognition with human information processing models that have been developed within Cognitive Science. The model presented reflects both elements of the framework. Conventional behaviors are partially coded in the predisposition of participants in a joint activity to expect certain points of coordination to develop during the course of the activity. The expected points of coordination that are commonly assumed form a design for an activity . Because of uncertainty, interruptions, and numerous other opportunities to get off-track and out-of-synch, the participants must work jointly and continuously to achieve conventional coordination.
One feature of the model is that the community improves its performance despite the fact that individual actors reason independently about their experiences. Another important feature of the model is that the mechanisms for improving behavior are tied to the memory function of individual actors. A third important feature is that the social interaction among the participants simplifies and drives the everyday reasoning processes. An analysis of a large set of computational experiments supports the theoretical position that is developed regarding everyday reasoning and convention.     

Adolescents' perceptions of outpatient mental health services

Thirty-three adolescents from three mental health service settings were interviewed regarding their perceptions of the purpose, goals, expectations, frustrations and benefits of mental health experiences. They provided satisfaction ratings and importance rankings of seven domains of satisfaction: (a) Convenient/Accessible, (b) Meeting Needs, (c) Staff Competence, (d) Personal Relationship with Staff, (e) Effectiveness of Treatment, (f) Comfort/Appropriateness of Center, and (g) Costs and Paperwork. In addition, participants completed the Client Satisfaction Questionnaire (CSQ-8). Results indicated that, in general, the adolescents were very satisfied with the services they received. Gender, race/ethnicity and treatment site were not related to satisfaction scores, nor was the adolescent's perceived choice in seeking services. Some significant gender differences were found both in terms of the rankings of satisfaction domains, as well as in the adolescents' perceptions of their reasons for initiating counseling and the perceived goals and benefits of counseling. Additional differences in perceptions of services were found for treatment site and race/ethnicity. In general, adolescents were able to generate informative, sophisticated responses to questions regarding their perceptions of mental health services, and demonstrated that they are capable of evaluating services they receive.     

The Effects of Piece-Rate Underpayment and Overpayment on Job Performance: A Test of Equity Theory with a New Induction Procedure1

An experiment was designed to test the following hypotheses derived from Equity Theory: (I) Underpaid pieceworkers will produce more work of lower quality than equitably paid pieceworkers and (II) Overpaid pieceworkers will produce less work of higher quality than equitably paid pieceworkcrs. Thirty-six males and 36 females were hired for a 1-hour proofreading job. Subjects were assigned randomly to receive 15, 30, or 60 cents per page. All subjects met another worker (really a confederate) who revealed that he was receiving 30 cents per page. This produced three experimental conditions: underpayment, equity, and overpayment. The principal dependent variables were number of pages read and proportion of errors detected by subjects. In general, the results provide strong support for Equity Theory. Males and females both performed in a manner consistent with the hypotheses, although females did tend to react less intensely than did males when overpaid.
