Self-enhancement and belief perseverance

Belief perseverance—the tendency to make use of invalidated information—is one of social psychology’s most reliable phenomena. Virtually all of the explanations proffered for the effect, as well as the conditions that delimit it, involve the way people think about or explain the discredited feedback. But it seems reasonable to assume that the importance of the feedback for the actor’s self-image would also influence the tendency to persevere on invalidated feedback. From a self-enhancement perspective, one might ask: Why would people persist in negative self-beliefs, especially when the basis for those beliefs has been discredited? In the present study, actors and observers completed a word-identification task and were given bogus success or failure feedback. After success feedback was discredited, actors and observers persevered equally in beliefs about the actor’s abilities. However, following invalidation of failure feedback, actors provided significantly higher performance evaluations than observers, thus exhibiting less perseverance on the negative feedback. These results suggest that the motivation to maintain a relatively favorable self-image may attenuate perseverance when discredited feedback threatens an important aspect of the self-concept.     

The (impossible) Future of Hermeneutics

ABSTRACT

This paper argues that the negativity of hermeneutic experience is revelatory for the following reasons. Hermeneutic failure is not the equivalent of making an erroneous step in a closed circuit of reasoning. Neither is it a refutation. It concerns becoming conscious of an omission, an oversight, an unjustifiable claim to completeness and even the displacement of one interpretation by another more suggestive. The negative dimension of hermeneutic failure is incontrovertibly connected with becoming progressively aware of how, contrary to expectations, a different way of seeing is possible: something comes to light which displaces one’s former judgement. Consciousness of failure is, then, indissociable from an emergent awareness of overlooked and unremarked ways of thinking: “I should have been alert to this” or “I failed to take account of that”. Consciousness of failure is revelatory precisely because something else and something other than my expectation has shown itself to be decisive and in so doing has displaced my former understanding. This is the basis of the claim that the educative and spiritual importance of hermeneutics lies precisely in the practical pursuit of the impossible. It is a key contention of the paper that hermeneutic understanding expands and extends itself as a consequence of its impossible quest for completion.     

Habit outweighs planning in grasp selection for object manipulation

Object-directed grasping movements are adapted to intended interactions with an object. We address whether adjusting the grasp for object manipulation is controlled habitually, based on past experiences, or by goal-directed planning, based on an evaluation of the expected action outcomes. Therefore, we asked participants to grasp and rotate a dial. In such tasks, participants typically grasp the dial with an excursed, uncomfortable arm posture, which then allows to complete the dial rotation in a comfortable end-state. We extended this task by manipulating the contingency between the orientation of the grasp and the resulting end-state of the arm. A one-step (control) group rotated the dial to a single target. A two-step group rotated the dial to an initial target and then in the opposite direction. A three-step group rotated the dial to the initial target, then in the opposite direction, and then back to the initial target. During practice, the two-step and three-step groups reduced the excursion of their grasps, thus avoiding overly excursed arm postures after the second rotation. When the two-step and three-step groups were asked to execute one-step rotations, their grasps resembled those that were acquired during the two-step and three-step rotations, respectively. However, the carry-over was not complete. This suggests that adjusting grasps for forthcoming object manipulations is controlled by a mixture of habitual and goal-directed processes. In the present experiment, the former contributed approximately twice as much to grasp selection than the latter.     

Using simultaneous presentation to increase vegetable consumption in a mildly selective child with autism

A multiple baseline design was used to evaluate the effects of adding condiments on the consumption of previously rejected foods (vegetables). Adding condiments produced increased food acceptance across three food items. Data are discussed in relation to conditioned food preferences and establishing operations.     

Affective consequences of optimism and pessimism in the face of failure: Evidence of a moderation by attribution

The present experiment set out to investigate the affective consequences of dispositional optimism and attribution in performance settings. Optimistic and pessimistic participants (N = 42 each) experienced failure at solving two cognitive tasks in an alleged team setting. The failure could either be attributed to themselves (internal condition) or a teammate (external condition). We found disordinal interactions of optimism and attribution on the feelings of success and feelings of failure. While the affective state of optimists deteriorated significantly if they attributed the failure internally compared to externally, pessimists were emotionally unaffected by the locus of attribution. Moreover, optimists experienced affective benefits compared to pessimists when they attributed the outcome externally. The reverse was true if they had attributed internally. Affective consequences of optimism and pessimism after failure therefore seem to differ depending on attributions. Furthermore, pessimists seemed to be unresponsive to the affective effects of attribution in our study. This insensitiveness implies differences in the cognitive processing of outcomes, a trait × cognition interaction that should be investigated further.     

Comparison of bite-presentation methods in the treatment of food refusal

The current study examined the rate of expulsions and mouth cleans across 3 presentation methods (upright spoon, flipped spoon, Nuk brush) for a 3-year-old girl with a feeding disorder. The participant expelled all bites presented on an upright spoon. Results showed reduced rates of expulsions and increased mouth cleans during the flipped spoon and Nuk brush presentation methods.     

The Effects of Domain Knowledge and Instructional Manipulation on Creative Idea Generation

The experiment was designed to explore the effects of domain knowledge, instructional manipulation, and the interaction between them on creative idea generation. Three groups of participants who respectively possessed the domain knowledge of biology, sports, or neither were asked to finish two tasks: imagining an extraterrestrial animal and creating a new sport. Participants in each group were randomly assigned to one of three instructions, in order to encourage them to perform the tasks using a specific instance strategy (relying on specific instances), an abstract strategy (relying on abstract principles), or their habitual ways. Based on an analysis of the participants' verbal reports and their creations, the results suggested that domain knowledge enhanced the tendency to use the abstract strategy, and improved the originality and practicality of the generated ideas. Instructions also influenced the strategy participants used in creative idea generation. The instruction to use abstract principles brought forth the most original creations. Moreover, there was an interaction between domain knowledge and instructions. Encouraging participants to use the specific instance strategy blocked the knowledgeable people from developing novel ideas. Other factors, such as age, grade and gender, were found to be unrelated to either the originality or the practicality of the creations. The implications of the results were discussed in detail.     

Self‐generated variability in object images predicts vocabulary growth

Object names are a major component of early vocabularies and learning object names depends on being able to visually recognize objects in the world. However, the fundamental visual challenge of the moment‐to‐moment variations in object appearances that learners must resolve has received little attention in word learning research. Here we provide the first evidence that image‐level object variability matters and may be the link that connects infant object manipulation to vocabulary development. Using head‐mounted eye tracking, the present study objectively measured individual differences in the moment‐to‐moment variability of visual instances of the same object, from infants’ first‐person views. Infants who generated more variable visual object images through manual object manipulation at 15 months of age experienced greater vocabulary growth over the next six months. Elucidating infants’ everyday visual experiences with objects may constitute a crucial missing link in our understanding of the developmental trajectory of object name learning.     

Increased pupil dilation during tip-of-the-tongue states

Tip-of-the-tongue states (TOTs) are feelings of impending word retrieval success during a current failure to retrieve a target word. Though much is known and understood about TOT states from decades of research, research on potential psychophysiological correlates of the TOT state is still in its infancy, and existing studies point toward the involvement of neural processes that are associated with enhanced attention, motivation, and information-seeking. In the present study, we demonstrate that, during instances of target retrieval failure, TOT states are associated with greater pupillary dilation (i.e., autonomic arousal) in 91% of our sample. This is the first study to demonstrate a pupillometric correlate of the TOT experience, and this finding provides an important step toward understanding emotional attributes associated with TOT states. Mean pupil dilation also increased such that instances of target identification failure that were unaccompanied by TOT states < instances in which TOTs occurred < instances of target identification success. It is possible that TOTs reflect an intermediary state between complete target retrieval failure and full target retrieval.
