Unresolved problems with the “I”, the “A”, and the “T”: A logical and psychometric critique of the Implicit Association Test (IAT)

The Implicit Association Test (IAT) had already gained the status of a prominent assessment procedure before its psychometric properties and underlying task structure were understood. The present critique addresses five major problems that arise when the IAT is used for diagnostic inferences: (1) the asymmetry of causal and diagnostic inferences; (2) the viability of the underlying association model; (3) the lack of a testable model underlying IAT-based inferences; (4) the difficulties of interpreting difference scores; and (5) the susceptibility of the IAT to deliberate faking and strategic processing. Based on a theoretical reflection of these issues, and a comprehensive survey of published IAT studies, it is concluded that a number of uncontrolled factors can produce (or reduce) significant IAT scores independently of the personality attribute that is supposed to be captured by the IAT procedure.

Mindfulness meditation counteracts self-control depletion

Mindfulness meditation describes a set of different mental techniques to train attention and awareness. Trait mindfulness and extended mindfulness interventions can benefit self-control. The present study investigated the short-term consequences of mindfulness meditation under conditions of limited self-control resources. Specifically, we hypothesized that a brief period of mindfulness meditation would counteract the deleterious effect that the exertion of self-control has on subsequent self-control performance. Participants who had been depleted of self-control resources by an emotion suppression task showed decrements in self-control performance as compared to participants who had not suppressed emotions. However, participants who had meditated after emotion suppression performed equally well on the subsequent self-control task as participants who had not exerted self-control previously. This finding suggests that a brief period of mindfulness meditation may serve as a quick and efficient strategy to foster self-control under conditions of low resources.

How Focusing on Superordinate Goals Motivates Broad, Long-Term Goal Pursuit: A Theoretical Perspective

Goal-setting theory states that challenging, specific, and concrete goals (i.e., subordinate goals) are powerful motivators and boost performance in goal pursuit more than vague or abstract goals (i.e., superordinate goals). Goal-setting theory predominantly focuses on single, short-term goals and less on broad, long-term challenges. This review article extends goal-setting theory and argues that superordinate goals also fulfill a crucial role in motivating behavior, particularly when addressing broad, long-term challenges. The purpose of this article is to shed light on the benefits of superordinate goals, which have received less attention in research, and to show theoretically that people pursue long-term goals more successfully when they focus on subordinate as well as superordinate goals than when they focus on either subordinate or superordinate goals alone.

Partitioning the Choice Task Makes Starbucks Coffee Taste Better

Consumers are often less satisfied with a product chosen from a large assortment than a limited one. Experienced choice difficulty presumably causes this as consumers have to engage in a great number of individual comparisons. In two studies we tested whether partitioning the choice task so that consumers decided sequentially on each individual attribute may provide a solution. In a Starbucks coffee house, consumers who chose from the menu rated the coffee as less tasty when chosen from a large rather than a small assortment. However, when the consumers chose it by sequentially deciding about one attribute at a time, the effect reversed. In a tailored-suit customization, consumers who chose multiple attributes at a time were less satisfied with their suit, compared to those who chose one attribute at a time. Sequential attribute-based processing proves to be an effective strategy to reap the benefits of a large assortment.

Der mittelfristige Einfluss von Feedback auf die Leistung von Mastery oder Performance motivierten Personen

In vielen Situationen bekommen Personen beim Lernen neuer Aufgaben in einer ersten Phase Feedback, doch in einer zweiten Phase arbeiten sie ohne Feedback. Bislang gibt es einige Befunde zu der Auswirkung eines Feedbacks auf die unmittelbare Leistung, nicht jedoch auf die mittelfristige Leistung in einer Phase ohne Feedback. Es ist zu erwarten, dass die Form der Leistungsmotivation hier eine entscheidende Rolle spielt. Fur Personen, die das Ziel haben, besser zu sein als andere, kann ein negatives Feedback eine Bedrohung des Selbstwertes darstellen und daher demotivieren. Mittelfristig sollte jedoch die Bedrohung des Selbstwertes abnehmen. Daher ist zu erwarten, dass Feedback mittelfristig die Leistung steigert. Fur Personen, die das Ziel haben, ihre Kenntnisse zu verbessern, stellt ein negatives Feedback keine Bedrohung des Selbstwertes da. Daher sollte sich Feedback anfanglich positiv auf die Leistung auswirken. Diese Personen lieben jedoch das Gefuhl, sich Kenntnisse selbst zu erarbeitet zu haben. Feedback verdirbt den Spass am selbststandigen Explorieren und Losungen finden. Feedback sollte daher - nach einer anfanglichen Leistungssteigerung- mittelfristig zu einer Verringerung der Leistung fuhren. Wir zeigen in einer Studie in der Tangram Puzzles gelost wurden, dass beide Prozesse stattfinden. (DIPF/Orig.)
