A spatial modality effect in serial memory

In 2 experiments, the authors tested whether the classical modality effect-that is, the stronger recency effect for auditory items relative to visual items-can be extended to the spatial domain. An order reconstruction task was undertaken with four types of material: visual-spatial, auditory-spatial, visual-verbal, and auditory-verbal. Similar serial position curves were obtained regardless of the nature of the to-be-remembered sequences, with the exception that a modality effect was found with spatial as well as with verbal materials. The results are discussed with regard to a number of models of short-term memory.     

Organization of visuo-spatial serial memory: interaction of temporal order with spatial and temporal grouping

This study investigates whether memory for sequences of spatial locations can be represented hierarchically, that is, as successive groups containing the order of constituent locations. Two grouping manipulations are used: Temporal grouping, based on the verbal serial memory literature, and spatial grouping, based on recent empirical work on visuo-spatial serial memory. In Experiment 1, we examine the relationship between spatial grouping and temporal order and showed that recall performance increases when both temporal and spatial organization correlate, but decreases when they clash. Experiments 2 and 3 show that the latter result is confounded by differences in path length (length of spatial path defined by the locations) between conditions, and that no effect of the spatial organization is observed when path length is controlled for. In Experiment 4, an alternative method to spatial grouping, temporal grouping, is used to induce hierarchical organization. A recall advantage is found in the temporal grouping condition. The results suggest that hierarchical representations can be imposed on order information for visuo-spatial sequences, either when participants have pre-existing knowledge about the form of the path formed by the sequence or when temporal boundaries delimit chunks; that increased path length is the cause of the performance decrement observed when dots from separate spatial groups are presented successively; and that path length and more generally sequence characteristics should be taken into account in designing future research on visuo-spatial serial memory.     

Articulatory complexity at item boundaries in serial recall: the case of Welsh and English digit span

The proposition that the difference in memory span between Welsh digits and English digits is accounted for by the longer articulatory duration of Welsh digits is critically reexamined. Two methods of measuring digit duration are contrasted. One is derived from digits spoken in isolation; the other is based on digits spoken in list format. Duration of Welsh digits was greater only when spoken in lists; with isolated production Welsh digits were significantly shorter than English digits. Also, span was shorter for Welsh digits. The results are interpreted in the light of the different articulatory demands made at the junctures between words in the English and Welsh lists. A supplementary experiment, using English words, illustrated that articulatory complexity at item boundaries increased serial recall error.     

Visual distraction and visuo-spatial memory: a sandwich effect

The functional characteristics of visuo-spatial serial memory and its sensitivity to irrelevant visual information are examined in the present study, through the investigation of the sandwich effect (e.g., Hitch, 1975). The memory task was one of serial recall for the position of a sequence of seven spatially and temporally separated dots. The presence of irrelevant dots interpolated with to-be-remembered dots affected performance over most serial positions (Experiment 1) but that effect was significantly reduced when the interpolated dots were distinct from the to-be-remembered dots by colour and shape (Experiment 2). Parallels are made between verbal and spatial serial memory, and the reduction of the sandwich effect is discussed in terms of the contribution of perceptual organisation and attentional factors in short-term memory.     

From auditory image to auditory percept: Facilitation through common processes?

Two experiments explored implicit memory for auditory stimuli as measured by a test of perceptual identification. The facilitative effect of perceived auditory primes was contrasted with that of imaged auditory primes. In Experiment 1, there was a significant priming effect from imaged spoken-word primes that did not differ significantly from the level of priming due to perceived spoken-word primes, measured by a test of auditory perceptual identification. There was no facilitation of spoken-word identification following creation of an image of a word’s referent sound. In Experiment 2, identification of an environmental sound was facilitated by prior processing of an imaged sound from the same category, though there was significantly more transfer following processing of the actual sound.

When Middle Really Means “Top” or “Bottom”: An Analysis of the 16PF5 Using Bock's Nominal Response Model

When self-report items with a Likert-type scale include a middle response option (e.g., Unsure, Neither agree nor disagree, or ?), this middle option is assumed to measure a level of the trait intermediate between the high and low response categories. In this study, we tested this assumption in the 16 Personality Factor Questionnaire, Version 5 (16PF5) by fitting Bock's nominal response model in the U.S. and UK standardization samples of the 16PF5. We found that in many cases, the middle option was indicative of higher levels of the latent trait than the ostensibly highest response option. In certain other cases, it was indicative of lower levels of the latent trait than the ostensibly lowest response option. This undermines the use of a simple successive integer scoring scheme where responses in adjacent response categories are assigned scores of 0, 1, and 2. Recommendations for alternative scoring schemes are provided. Results also suggested that certain personality traits, especially neurotic traits, are associated with a tendency toward selecting the middle option.     

“The indestructible,the barbaric principle”: The Role of Schelling in Merleau-Ponty’s Psychoanalysis

The aim of this paper is to examine Merleau-Ponty’s idea of a “psychoanalysis of Nature” (Merleau-Ponty in The visible and the invisible. Northwestern University Press, Evanston, 1968). My thesis is that in order to understand the creation of a Merleau-Pontean psychoanalysis (together with the role the unconscious plays in this psychoanalysis), we need to ultimately understand the place of Schelling in Merleau-Ponty’s late thought. Through his dialogue with Schelling, Merleau-Ponty will be able to formulate not only a psychoanalysis of Nature, but also fulfil the ultimate task of phenomenology itself; namely, of identifying “what resists phenomenology—natural being, the ‘barbarous’ source Schelling spoke of” and situating it precisely at the heart of phenomenology (Merleau-Ponty in Signs. Northwestern University Press, Evanston, p 178, 1964b). The plan for studying this natural psychoanalysis is threefold. First, I provide an overview of the role psychoanalysis plays in the 1951 lecture, “Man and Adversity,” focusing especially on this lecture as a turning point in his thinking. Second, I chart how Merleau-Ponty’s psychoanalysis is informed by the various ways in which the unconscious is formulated in his thought, leading eventually to a dialogue with Schelling. Accordingly, in the final part of the paper, I trace the role of Schelling’s thought in the creation of a Merleau-Pontean psychoanalysis. As I argue, what distinguishes this psychoanalysis is the centrality of Schelling’s idea of the “barbaric principle,” which manifests itself as the notion of an unconscious indexing an “excess of Being” resistant to classical phenomenology (Merleau-Ponty in Nature: course notes from the college de France. Northwestern University Press, Evanston, p 38, 2003).     

Nonlinear Indicator-Level Moderation in Latent Variable Models

Linear, nonlinear, and nonparametric moderated latent variable models have been developed to investigate possible interaction effects between a latent variable and an external continuous moderator on the observed indicators in the latent variable model. Most moderation models have focused on moderators that vary across persons but not across the indicators (e.g., moderators like age and socioeconomic status). However, in many applications, the values of the moderator may vary both across persons and across indicators (e.g., moderators like response times and confidence ratings). Indicator-level moderation models are available for categorical moderators and linear interaction effects. However, these approaches require respectively categorization of the continuous moderator and the assumption of linearity of the interaction effect. In this article, parametric nonlinear and nonparametric indicator-level moderation methods are developed. In a simulation study, we demonstrate the viability of these methods. In addition, the methods are applied to a real data set pertaining to arithmetic ability.     

Motives matter: The emotional consequences of recalled self- and other- focused prosocial acts

Past research has demonstrated that engaging in and reflecting upon past instances of prosocial behavior promote happiness. Yet, people provide help for a myriad of reasons. Do the motives for giving impact its emotional consequences? In three experiments (N?>?680), we compared the emotional outcomes of recalling a past instance of prosocial behavior motivated by self-focused and other-focused concerns. Using both between and within subjects designs, we find that recalling an instance of other-focused helping leads to higher positive affect than recalling an instance of self-focused helping. This finding was mediated by feelings of morality. The present work suggests that not all acts of kindness offer equivalent well-being benefits and that selfish motives may undermine the emotional rewards that typically follow other-focused prosocial behavior.
