Examining Project Commitment in Cross-Functional Teams: Antecedents and Relationship with Team Performance

Purpose

The purpose of this study was to test a model positing both antecedents and consequences of project commitment for members of cross-functional teams. Signaling theory and previous research guided study hypotheses.

Design/Methodology/Approach

We collected primary data from 142 team members and 31 team leaders across 24 cross-functional product development teams nested within six manufacturing organizations in the US and Canada.

Findings

Findings suggest that project commitment among team members is an important driver of team performance as rated by the team leader. In addition, several factors contribute toward shaping project commitment among cross-functional team members, including team leaders’ encouragement of self-expectation, as well as team members’ perceptions of an organization’s support for the team project.

Implications

Cross-functional teams are often charged with completing projects critical to the profitability, growth, and even survival of a firm. Especially as we show that members’ project commitment is a meaningful predictor of team performance, managers may draw insight from study results as to what actions may be taken to promote the development of this important psychological state among members of cross-functional teams.

Originality/Value

Use of cross-functional teams for accomplishing a wide variety of firm objectives is becoming commonplace in organizations. Although theorized as an important construct in cross-functional team settings, empirical examinations of the nature and implications of project commitment have been limited. By examining both antecedents and potential team performance consequences of project commitment in multiple organizations, we contribute toward filling this gap.     

Using continuous heart rate monitoring to investigate anxiety and its communication with the dentist–patient interaction

Abstract

The importance of communication within the dentist–patient relationship has long been recognised with regard to patient satisfaction and anxiety. However there has been little research into the anxiety experienced by both patient and dentist during the administration of dental treatment nor how such affects are perceived and communicated within the dentist–patient interaction.

The study reported here, examined affective communication between dental students (n=16) and their patients (n=64) by using continuous and simultaneous cardiovascular monitoring during an entire dental treatment session. The data was analysed using stepwise regression analysis together with the development of a measure of emotionality in order to understand the communication of anxiety during dental treatment procedures. The results suggested that anxiety was communicated between dental operator and patient but was dependent on the degree of clinical experience of the operator.     

Real-space first-principles electronic structure of edge dislocations: NiAl

The electronic structure of the 100 {010} edge dislocation in NiAl has been calculated using the real-space tight-binding linear muffin-tin orbital recursion method with a self-consistent treatment of electron density redistribution effects in the dislocation core. We demonstrate that quasilocalized states may exist in this metallic system as a result of specific lattice distortions in the dislocation core with 'broken bonds'.     

Young children who abandon error behaviourally still have to free themselves mentally: a retrospective test for inhibition in intuitive physics

When preschoolers overcome persistent error, subsequent patterns of correct choices may identify how the error had been overcome. Children who no longer misrepresented a ball rolling down a bent tube as though it could only fall vertically, were asked sometimes to approach and sometimes to avoid where the ball landed. All children showed requisite task-switching flexibility. The pattern of 4-year-olds' correct choices among different places showed unnecessary avoidance of any place that would previously have tempted them into a vertical-approach error, 5-year-olds rebounded into a reversal, and 7-year-olds were flexible. The data attest to an inhibition mechanism, ruling out competing possibilities.     

Distinctiveness models of memory and absolute identification: evidence for local, not global, effects

Many models of memory assume that the probability of remembering an item is related to how distinctive that item is relative to all the other items in the set, with no distinction made between the contributions of near or far items. These “global” distinctiveness models do well in accounting for the ubiquitous serial position effects observed in numerous memory paradigms, including absolute identification. Here, we provide experimental confirmation of Bower's (1971) suggestion that, contrary to a fundamental prediction of global distinctiveness models, midseries items can be more discriminable than their immediate neighbours. We show that such data are consistent with a revised distinctiveness account in which the factor affecting discrimination performance is primarily the distinctiveness of an item relative to its close neighbours.     

The distribution and development of handedness for manual gestures in captive chimpanzees (Pan troglodytes)

This article describes the distribution and development of handedness for manual gestures in captive chimpanzees. Data on handedness for unimanual gestures were collected in a sample of 227 captive chimpanzees. Handedness for these gestures was compared with handedness for three other measures of hand use: tool use, reaching, and coordinated bimanual actions. Chimpanzees were significantly more right-handed for gestures than for all other measures of hand use. Hand use for simple reaching at 3 to 4 years of age predicted hand use for gestures 10 years later. Use of the right hand for gestures was significantly higher when gestures were accompanied by a vocalization than when they were not. The collective results suggest that left-hemisphere specialization for language may have evolved initially from asymmetries in manual gestures in the common ancestor of chimpanzees and humans, rather than from hand use associated with other, non-communicative motor actions, including tool use and coordinated bimanual actions, as has been previously suggested in the literature.     

The influence of unimanual response on pseudoneglect magnitude

Various factors influence the degree of leftward error (pseudoneglect) (Bowers & Heilman, 1980) that typifies the performance of normal subjects in line bisection tasks (Jewell & McCourt, 2000). The results of this experiment show that unimanual responding also exerts a subtle but significant modulating influence on spatial attention, as indexed by the differential magnitude of pseudoneglect. Using a forced-choice tachistoscopic line bisection protocol, 184 subjects (92 male and 92 female) bisected horizontally oriented lines (22.3 degrees wide x 0.39 degrees height) presented to central vision in two conditions, in which bisection responses were executed via button presses using the first two fingers of either the left (LH) or right (RH) hand. Perceived line midpoint deviated significantly leftward of veridical (p <.05) in both conditions. There was no significant influence of subject sex (p >.05). A significant influence of unimanual response was revealed (p <.05) where pseudoneglect magnitude was greater in the LH than the RH condition. The results are interpreted within the framework of the activation-orientation theory of attentional asymmetry.     

Involvement of the sigma receptor in passive-avoidance learning in the day-old chick during the second wave of neuronal activity

The specific sigma-receptor agonist (+)-SKF 10047 and antagonist BD 1047 were used to investigate whether this receptor was involved in passive-avoidance training in the day-old chick. We found 300 microM (+)-SKF 10047 to be amnesic when injected into the lobus parolfactorius 5 h after training (p < .01). Higher or lower concentrations of (+)-SKF 10047 did not disrupt memory formation. The amnesia produced by the efficacious dose of (+)-SKF 10047 was reversed by the specific antagonist, BD 1047. It is suggested that the sigma-receptor may exert its effect on passive-avoidance memory consolidation during the later stages of long-term memory formation by modulation of memory-related neurotransmission.
