Paradoxical effects of testing: retrieval enhances both accurate recall and suggestibility in eyewitnesses

Although retrieval practice typically enhances memory retention, it can also impair subsequent eyewitness memory accuracy (Chan, Thomas, & Bulevich, 2009). Specifically, participants who had taken an initial test about a witnessed event were more likely than nontested participants to recall subsequently encountered misinformation—an effect we called retrieval-enhanced suggestibility (RES). Here, we sought to test the generality of RES and to further elucidate its underlying mechanisms. To that end, we tested a dual mechanism account, which suggests that RES occurs because initial testing (a) enhances learning of the later misinformation by reducing proactive interference and (b) causes the reactivated memory trace to be more susceptible to later interference (i.e., a reconsolidation account). Three major findings emerged. First, RES was found after a 1-week delay, where a robust testing benefit occurred for event details that were not contradicted by later misinformation. Second, blockage of reconsolidation was unnecessary for RES to occur. Third, initial testing enhanced learning of the misinformation even when proactive interference played a minimal role.     

Executive functioning and prospective memory in young children

The current study examined the role of executive functioning (EF) in children's prospective memory (PM) by assessing the effect of delay and number of intentions to-be-remembered on PM, as well as relations between PM and EF. Ninety-six 4-, 5-, and 6-year-olds completed a PM task and two executive function tasks. The PM task required children to interrupt an ongoing card game to perform one action (single intention) or two actions (dual intention) with target cards after a short delay (1 min) or a long delay (5 min). There was no main effect of number of intentions or delay on the PM task. However, performance improved with age, and age and delay interacted such that 4-year-olds’ performance remained the same after a long delay whereas 5-year-olds’ performance improved after a long delay. We suggest that the age by delay interaction is a product of age differences in cognitive monitoring. Working memory but not inhibitory control predicted PM with age controlled. We argue that an executive function framework permits an integrative understanding of many processes involved in young children's prospective memory.     

Picture recognition without picture identification: a method for assessing the role of perceptual information in familiarity-based picture recognition

The present study examined the claim that unidentifiable test-pictures are processed and recognized on a perceptual, as opposed to a conceptual, level. Using an extension of the recognition without identification paradigm (e.g., Cleary, A. M. & Greene, R. L. (2000). Recognition without identification. Journal of Experimental Psychology: Learning, Memory, and Cognition, 26, 1063-1069; Peynircioglu, Z. F. (1990). A feeling-of-recognition without identification. Journal of Memory and Language, 29, 493-500), it was observed that when test-pictures were unidentifiable during a masked perceptual identification task, old-new discrimination occurred when the study-list consisted of pictures (Experiments 1-3), but not when the study-list consisted of picture names (Experiment 2) or when picture exemplars served as test-cues (Experiment 3). Results provide converging evidence that a study-test perceptual match is needed for the episodic recognition of unidentified test-pictures. Implications for the present paradigm as a tool for examining the role of perceptual information in recognition-familiarity are discussed.     

Luther and Shankara: Two Ways of Salvation in the Indian Context

Abstract : This article compares and contrasts the soteriology of Reformer Martin Luther with Advaita philosopher Shankara. Luther's emphasis on the communication of attributes (communicatio idiomatum) in the two natures of Christ gets doubled in faith, where the indwelling Christ takes on our human nature while giving the believer the fruits of his divine nature, such as eternal life. Conversely, our human finite history replete with suffering is taken up into the divine life, dignifying what is mundanely human. In the Indian tradition of the Upanishads and nonduality in philosophy, Shankara seeks the union of the Self (atman) with the highest reality, the Absolute (Brahman). The realization of the oneness of Self with Brahman requires the shedding of all historical or personal attributes. The result is that the suffering of oppressed untouchables and other lower castes is dubbed unreal. A healthy soteriology in the context of Indian spirituality—a Dalit soteriology—could benefit from Luther's exchange of attributes, because the mundane sufferings of humble people are dignitifed by receiving a place in God's reality.     

Multicultural Education as Fostering Individual Autonomy

This article attempts a philosophical defense of an autonomy-based approach to multicultural education. I contend that multicultural education is necessary in order for students to be able to develop personal autonomy. This, in turn, can empower students to effectively formulate their own version of the good life. The development of autonomy need not, as many critics claim, promote atomistic individualism. Rather, contemporary liberal autonomy strives for a balance between the individual and the community. In defending multicultural education, my argument relies on Joseph Raz's notion of autonomy and Will Kymlicka's concept of a context of choice. I conclude that through multicultural education, students can expand their contexts of choice and consequently develop individual autonomy, an essential ingredient of the good life.     

A SELF-INSTRUCTIONAL PACKAGE FOR INCREASING ATTENDING BEHAVIOR IN EDUCABLE MENTALLY RETARDED CHILDREN

The purpose of this study was to develop a self-instructional package that would aid highly distractible retarded children in increasing their attending behavior in a training and two generalization (a one-to-one and a classroom) situations. Three untrained subjects were monitored for general comparison and social validation purposes. One of these control subjects was distractible and the other two (criterion comparison) were evaluated as not having attentional problems. A multiple baseline design was employed in which training was sequentially introduced across subjects. During training, the experimental subjects were taught through self-instruction to focus their attention and to cope with two tasks, math and printing. After learning the self-instructions the subjects were systematically and sequentially exposed to photo-slides of distracting situations, to audio-distractors composed of noisy lunchroom verbal peer interactions, and to in vivo distractors provided by kindergarten children playing with wooden blocks in the training setting. The entire training procedure was handled in a game-like context to maintain subject interest and to facilitate generalization. The results suggested that the training package produced direct and generalized changes in self-instructional behavior. In addition, a decrease in off-task behavior occurred during math, printing, and also during a phonics program in the one-to-one and classroom situations. However, reliable changes in academic task performance were not observed. Finally, no systematic changes on any of the dependent measures occurred for the three untrained subjects.
