How to Measure Motivation: A Guide for the Experimental Social Psychologist

This article examines cognitive, affective, and behavioral measures of motivation and reviews their use throughout the discipline of experimental social psychology. We distinguish between two dimensions of motivation (outcome‐focused motivation and process‐focused motivation). We discuss circumstances under which measures may help distinguish between different dimensions of motivation, as well as circumstances under which measures may capture different dimensions of motivation in similar ways. Furthermore, we examine situations in which various measures may capture fluctuations in non‐motivational factors, such as learning or physiological depletion. This analysis seeks to advance research in experimental social psychology by highlighting the need for caution when selecting measures of motivation and when interpreting fluctuations captured by these measures.     

Domesticated dogs’ (Canis familiaris) use of the solidity principle

Organisms must often make predictions about the trajectories of moving objects. However, often these objects become hidden. To later locate such objects, the organism must maintain a representation of the object in memory and generate an expectation about where it will later appear. We explored adult dogs’ knowledge and use of the solidity principle (that one solid object cannot pass through another solid object) by evaluating search behavior. Subjects watched as a treat rolled down an inclined tube into a box. The box either did or did not contain a solid wall dividing it in half. To find the treat, subjects had to modify their search behavior based on the presence or absence of the wall, which either did or did not block the treat’s trajectory. Dogs correctly searched the near location when the barrier was present and the far location when the barrier was absent. They displayed this behavior from the first trial, as well as performed correctly when trial types were intermingled. These results suggest that dogs direct their searches in accordance with the solidity principle.     

When waiting to choose increases patience

We explore how waiting to choose influences patience. We propose that waiting to make an intertemporal choice increases the assumed value of the items for which people are waiting, leading them to become more patient. Five studies support this model. Study 1 finds that after waiting to choose, people exhibit greater patience than if they had not waited or before they had started to wait. Studies 2a and 2b find that increased valuation (rather than decreased cost of the wait) mediates the impact of waiting on patience. Study 3 further finds that whereas waiting to choose increases preference for a larger-later (over smaller-sooner) item, it also increases willingness to pay to expedite delivery of a single item. Finally, study 4 shows the waiting effect is stronger for hedonic than for utilitarian products. These studies modify existing theory by identifying the conditions under which waiting to choose can improve patience.     

Searching for the Right Word: Performance on Four Word-Retrieval Tasks Across Childhood

Word retrieval was assessed in 207 normally developing Hebrew-speaking children aged 8–17 through four tasks: picture naming, phonemic fluency, semantic fluency, and homophone meaning generation (HMGT). Scores on all tests correlated positively and significantly with participant age. Yet, age effects and the correlation between age and test scores were weakest for the naming test and strongest for the HMGT. We discuss the nature of the word search involved in each task and suggest that the more executive demands required by a test the steeper the slope of performance increase on this test.     

How Positive and Negative Feedback Motivate Goal Pursuit

This article explores the feedback individuals give, seek, and respond to in the course of pursuing their goals. We propose that positive feedback motivates goal pursuit when it signals an increase in goal commitment, whereas negative feedback motivates goal pursuit when it signals insufficient goal progress. We review research suggesting that whether individuals are drawn to evaluate their level of commitment versus rate of progress determines the type of feedback (positive or negative) that best motivates them to pursue their goals. We then review research suggesting that these effects of feedback operate by inducing positive and negative general moods as well as specific emotions.     

Important questions remain to be addressed before adopting a dimensional classification of mental disorders

Comments on the original article "Plate tectonics in the classification of personality disorder: Shifting to a dimensional model," by T. A. Widiger and T. J. Trull. Widiger and Trull raised important nosological issues that warrant serious consideration not only for the personality disorders but for all mental disorders as the Diagnostic and Statistical Manual of Mental Disorders (DSM) is revised during the next few years. As argued compellingly by these authors, dimensional classification may indeed offer substantial improvement over the present categorical system. Several questions remain to be addressed in evaluating whether this is the case and, if so, how dimensional classification can be implemented to best serve the disparate users of the DSM.     

Attentional and perceptual factors affecting the attentional blink for faces and objects

When 2 different visual targets presented among different distracters in a rapid serial visual presentation (RSVP) are separated by 400 ms or less, detection and identification of the 2nd targets are reduced relative to longer time intervals. This phenomenon, termed the attentional blink (AB), is attributed to the temporary engagement of a limited-capacity attentional system by the 1st target, which reduces resources available for processing the 2nd target. Although AB has been reliably obtained with many stimulus types, it has not been found for faces (E. Awh et al., 2004). In the present study, the authors investigate the underpinnings of this immunity. Unveiling circumstances in which AB occurs within and across faces and other categories, the authors demonstrate that a multichannel model cannot account for the absence of AB effects on faces. The authors suggest instead that perceptual salience of the face within the distracters' series as well as the available resources determine whether or not faces are blinked in RSVP.     

Seeing bad does good: Relational benefits of accuracy regarding partners’ negative moods

When would greater empathic accuracy (EA) be an asset and when would it not? In two studies of romantic couples (both employing daily diaries, the second also involving a lab-based video-recall paradigm), we explored the associations between EA (at the day-level, person-level, and in the lab) and an important relationship outcome: negative relationship feelings. Our results show that accuracy is tied more strongly to this relational outcome when negative (vs. positive) moods are the target of empathic judgments. The association between accuracy and (better) feelings was true for both perceivers and targets. Importantly, these associations emerged only in diary-based accuracy scores, and not in the lab-based ones. These results further support the importance of everyday empathic accuracy. They also highlight the need to consider such accuracy as multi-faceted, and in particular, to recognize the differential role of attending to our partners’ negative versus positive moods in daily life.
