Collecting Narrative Data on Amazon's Mechanical Turk

Memory researchers collect data using Amazon's Mechanical Turk (AMT). Despite numerous reports documenting the reliability of data collected on this web site, no study of its uses for narrative memory research has been published. Participants reported narratives of stressful events and were recruited via AMT and in various formats with college students, including completing Internet surveys, typing in the presence of an experimenter, and verbal reports to the experimenter. Data were compared on linguistic indicators, event type reported, and questionnaire responses about these event narratives. AMT participants reported shorter event narratives than all groups of college students but reported stressful events that they self‐reported as more difficult than college students reporting via the Internet and used proportionally more negative emotion terms than college students reporting verbally to an experimenter. Factors such as context and demographics are considered, and recommendations are made for researchers using this web site. Copyright © 2015 John Wiley & Sons, Ltd.     

Gender differences in autobiographical memory: Developmental and methodological considerations

Gender differences have surfaced in inconsistent ways in autobiographical memory studies. When apparent, researchers find gender differences such that women report more vivid memory experiences than men and women include more details about emotions, about other people, and about the meaningfulness of their memories. Specifically, females include more emotion, more elaboration, and a greater sense of connectedness to others in their narratives, and we consider the possible connection between these tendencies and women’s advantage on a number of autobiographical and episodic memory tasks. However, not all studies of autobiographical memory find gender differences. We propose that gender differences in autobiographical memory development and interpersonal socialization contribute to the differences found, and that gender differences can be attributed, at least in part, to the influence of conversations with parents when autobiographical memory skills are developing. An examination of studies in which gender differences are not found suggests that specific instructions, context, gender salience, and the type of autobiographical memory measure used can mitigate gender differences. We conclude by outlining future directions for research, including longitudinal studies and experiments designed to systematically examine gender in autobiographical memory for its own sake.     

Gender Identity Predicts Autobiographical Memory Phenomenology

Gender differences emerge regularly in autobiographical memory research. We suggest that gender differences in phenomenological self‐report measures of autobiographical memory are rooted in gender identity rather than categorical gender. Reminiscing about the past is perceived as a female‐typical activity, and therefore, gender‐typical individuals will conform to these stereotypes. In this study, 196 participants, age 18–40, each rated the phenomenology of four event memories. Ratings of feminine gender identity, also completed by participants, consistently correlated with MEQ scores, indicating that greater endorsement of feminine gender norms predicted higher memory quality and valence. Masculine gender identity also correlated with MEQ scores, but these correlations were less consistent. Findings suggest that a focus on gender identity can both explain the source of some gender differences in autobiographical memory and potentially explain some inconsistencies in the current literature.Copyright © 2016 John Wiley & Sons, Ltd.     

The self in autobiographical memory: effects of self-salience on narrative content and structure

Contemporary models of autobiographical memory attribute a prominent role to the conceptualisation of the self. In an attempt to better understand the impact of the self as an organising feature of autobiographical memory, narratives of personal episodes were elicited, either after a questionnaire about the self (self-prime condition) or after a distractor task (control condition). Participants also wrote a narrative of a turning-point memory, which is by definition a self-focused narrative. Narratives were divided into propositions and analysed for the types of statements used. As predicted, when writing self-focused turning-point narratives participants included more statements relating to the meaning of an event and connecting it to the self, and fewer statements focusing on the who, what, where, and when of the narrative. Narratives written after the self-prime also demonstrated characteristics that were similar to turning-point narratives, although not on all measures. This shift in narrative focus in turning-point and self-primed memory narratives indicates an increased attempt to fulfil goals of coherence rather than correspondence (Conway, 2005). These findings lend insight into the nature of the relationship between the semantic conceptualisation of the self, and the process of retrieving event-specific knowledge in episodic memory.     

Pyramid algorithms for perceptual organization

Multiresolution (orpyramid) approaches to computer vision provide the capability of rapidly detecting and extracting global structures (features, regions, patterns, etc.) from an image. The human visual system also is able to spontaneously (orpreattentively) perceive various types of global structure in visual input; this process is sometimes calledperceptual organization. This paper describes a set of pyramid-based algorithms that can detect and extract these types of structure; included are algorithms for inferring three-dimensional information from images and for processing time sequences of images. If implemented in parallel on cellular pyramid hardware, these algorithms require processing times on the order of the logarithm of the image diameter.     

Emotion,gender, and gender typical identity in autobiographical memory

Gender differences in the emotional intensity and content of autobiographical memory (AM) are inconsistent across studies, and may be influenced as much by gender identity as by categorical gender. To explore this question, data were collected from 196 participants (age 18–40), split evenly between men and women. Participants narrated four memories, a neutral event, high point event, low point event, and self-defining memory, completed ratings of emotional intensity for each event, and completed four measures of gender typical identity. For self-reported emotional intensity, gender differences in AM were mediated by identification with stereotypical feminine gender norms. For narrative use of affect terms, both gender and gender typical identity predicted affective expression. The results confirm contextual models of gender identity (e.g., Diamond, 2012 Diamond, L. M. (2012). The desire disorder in research on sexual orientation in women: Contributions of dynamical systems theory. Archives of Sexual Behavior, 41, 73–83. doi: 10.1007/s10508-012-9909-7[Crossref], [PubMed], [Web of Science ®] , [Google Scholar].
