A focus on commitment: the roles of transformational and transactional leadership and self-regulatory focus in fostering organizational and safety commitment

The concept of employees’ commitment is one of the most challenging concepts in the management, organizational behaviour and human resource management literatures and research. The current study focuses on the construct of commitment as an emotional attitude, and expands the concept of general organizational commitment to a new more specific form of commitment, commitment to safety. Furthermore, commitment theorists commonly identify leadership as an important contributing factor to the development of organizational commitment. We aim to explain an underlying motivational mechanism, self-regulatory foci, through which leadership styles foster followers’ commitment. Results of three studies that used different methods (field and experimental), within different samples, demonstrated that transformational leadership was positively associated with followers’ promotion focus, which in turn was positively associated with both followers’ general and affective commitment to safety. Prevention focus mediated the positive relationship between a transactional active leadership style and both followers’ general and continuance commitment to safety. The implications of the findings for theory and practice are further discussed.     

On the perceptual specificity of memory representations

The present paradigm involved manipulating the congruency of the perceptual processing during the study and test phases of a recognition memory task. During each trial, a gaze-contingent window was used to limit the stimulus display to a region either inside or outside a 10 degrees square centred on the participant's point of gaze, constituting the Central and Peripheral viewing modes respectively. The window position changed in real time in concert with changes in gaze position. Four experiments documented better task performance when viewing modes at encoding and retrieval matched than when they mismatched (i.e., perceptual specificity effects). Viewing mode congruency effects were demonstrated with both verbal and non-verbal stimuli. The present research is motivated and discussed in terms of theoretical views proposed in the 1970s including the levels-of-processing framework and the proceduralist viewpoint. In addition, implications for current processing and multiple systems views of memory are outlined.     

Probing the Brain Substrates of Cognitive Processes Responsible for Context Effects on Recognition Memory

ABSTRACT

Context effects on episodic recognition memory involve separable contributions of target-context binding, additive familiarity, and configural constancy. Here we examine whether these factors reflect contributions of processes attributed to different brain substrates. First, we challenged frontal and medial temporal lobe-based cognitive capacities in healthy young adults, employing divided attention tasks at encoding and retrieval, and extended retrieval delay, respectively. Target-context binding effects were specifically attenuated by delay, but not by divided attention. In a second experiment, older adults were identified by neuropsychological testing as having different levels of frontal and medial temporal lobe-dependent cognitive functions. Consistent with Experiment 1, older adults with low medial temporal lobe function exhibited reduced target-context binding effects, but levels of frontal function did not modulate binding effects. These findings indicate that unlike source memory, context effects on memory are associated with the integrity of medial temporal lobe-based processes but not with the integrity of frontal lobe-based processes. Our findings also emphasize the importance of discriminating between functional subgroups in the attempt to characterize memory processes in older adults.     

“On That Day,His Feet Will Stand on the Mount of Olives”: The Mount of Olives and Its Hero between Jews,Christians, and Muslims

This article examines the changing Jewish attitudes toward the Mount of Olives, and toward the identification of its “hero” to come in the last days, in relation to the mount’s changing jurisdiction under Roman, Byzantine, and Muslim authority. It illustrates how the Christian appropriation of biblical ideas about the mountain—transforming the ascent and future descent of the Shekhinah into the ascent and future descent of Jesus—led the Jews to abandon those notions, and how the Muslim conquest then brought about a reinvigoration and expansion of the mountain’s original associations among Jews by relocating the appearance of the Messiah as well as apocalyptic scenes on the mount. In the first of these developments, the Byzantine prohibition against Jews approaching Jerusalem led to a distancing of the Jewish people from the biblical and postbiblical traditions that had been connected with the Mount of Olives and its environs during the Second Temple period. Subsequently, the Muslim occupation of the area neutralized that tension, allowing Jews to return to the mountain and restoring the traditions associated with it to the Jewish consciousness. The reaffirmation of the Jewish connection with the Mount of Olives and its ancient association with the future hero may be seen in two developments that took place under Muslim rule: its choice as the location for a yearly Hoshana Rabbah ceremony and its renewed identification as the site for the resurrection of the dead at the End of Days.     

Do object-category selective regions in the ventral visual stream represent perceived distance information?

It is well established that scenes and objects elicit a highly selective response in specific brain regions in the ventral visual cortex. An inherent difference between these categories that has not been explored yet is their perceived distance from the observer (i.e. scenes are distal whereas objects are proximal). The current study aimed to test the extent to which scene and object selective areas are sensitive to perceived distance information independently from their category-selectivity and retinotopic location. We conducted two studies that used a distance illusion (i.e., the Ponzo lines) and showed that scene regions (the parahippocampal place area, PPA, and transverse occipital sulcus, TOS) are biased toward perceived distal stimuli, whereas the lateral occipital (LO) object region is biased toward perceived proximal stimuli. These results suggest that the ventral visual cortex plays a role in representing distance information, extending recent findings on the sensitivity of these regions to location information. More broadly, our findings imply that distance information is inherent to object recognition.     

Communicative Behaviors of Outperformers and Their Perception by the Outperformed People

Four studies explored the communicative behaviors of people who outperform others in a relevant or irrelevant field and the impression formed of these outperformers by the outperformed people. In line with the premises of the self‐evaluation maintenance model ( A. Tesser, 1988 ) and the STTUC framework ( J. J. Exline & M. Lobel, 1999 ), Studies 1 and 2 predicted and found that people tend to conceal their achievements in conversation with a person whom they have outperformed, especially when the field of performance is relevant to this individual and irrelevant to them. Studies 3 and 4 found that the perception of outperformers is dependent not only on their communicative behaviors following the success but also on the relevance of the field for them and for the perceivers.     

Indirect Ingratiation: Pleasing People by Associating Them with Successful Others and by Praising Their Associates

Most of the literature on impression management considers direct tactics such as self‐promoting by mentioning personal achievements and ingratiating by complimenting others. These direct tactics can backfire if the target recognizes the hidden motive behind them. Therefore, people often use indirect impression management tactics. Previous research has shown that people promote themselves indirectly by associating themselves with successful others or by magnifying the characteristics of others to whom they are connected. The current research suggests that when the motive is ingratiation, the impression manager highlights the success of a person who is close to the target of ingratiation. The four experiments of the current research documented this tactic and examined its consequences for the impression manager and for the target.     

Driver fatigue among military truck drivers

The Israeli Defense Force (IDF) Transport Center is the largest and the most diverse transportation organization in Israel: three times as large as the largest commercial fleet in Israel, and military bases are spread all over the country. It also has the ability to regulate the drivers better: enforcing diet, hours of sleep, and working hours. The drivers are either permanently employed civilians, career service personnel, or mandatory service personnel. This employment status correlates with age, experience, carrier type, and several job characteristics (for example mandatory service drivers typically do not drive at night).The study consisted of a survey of 314 male drivers (30% of the entire base driver population). Despite the different environment, the military drivers display many characteristics and coping-behaviors characteristic of civilian drivers. Our results cast a doubt on the efficacy of enforcing night sleep and prohibiting night drives as an alternative to regulating hours of service. Our findings also reveal that it is insufficient to provide drivers with the time to sleep. One has to ensure that they also get a good quality of sleep. Implications for reducing fatigue in this environment are suggested. We identified the mandatory service drivers (young, less experienced drivers, lower military ranks) as a group of drivers that falls asleep more often and to a greater extent. They are particularly sensitive to sleep deficits and influenced by external events such as aggravation and boredom.It is important to provide drivers with more in-vehicle, accessible countermeasures to counter fatigue since they often do not stop, particularly in short-haul conditions. Since the radio has a high level of usage and acceptance among drivers, it could be exploited as an interactive communications system, as an educational medium, and as an image-enhancing device.
