“A Golly was simply a toy. End of”: Inoculation,attention deflection,and attempted puzzle-resolution in contesting racism in online discussions

In producing arguments against minority groups that are designed to avoid accusations of prejudice, speakers routinely deploy two discursive strategies. One strategy of “inoculation” seeks to ward off such accusations, while the other strategy of “attention deflection” directs attention away from the potential target group. Where despite use of one or both strategies accusations arise, the result is a puzzle that needs to be resolved through explanation. Here, in a discourse analysis of online discussions as to whether “blacking up” is to count as racism, we see contributors contest (a) whether absence of intention to offend inoculates individuals from accountability for potentially racist actions, (b) whether “blacking up” depicts toys/characters rather than people, and (c) whether attempted explanations of accusations of racism work to resolve the apparent puzzle that has arisen. Contributors do not reach any consensus. These findings point to the difficulties in attempting to challenge potential racism.     

Imaging the future: Does a qualitative analysis add to the picture?

Various studies report that patients with dense amnesia experience difficulties in simulating future events. It is argued that this resembles an inability to remember past episodes in that both indicate a deficit in mental scene construction. Such findings, however, rely upon quantitative content-based analyses of participants' verbal reports. Here, samples of verbal reports produced by participants with hippocampal lesions are subjected to a qualitative, discourse analysis of how participants and researchers negotiated the status of these reports. This shows that failure in mental scene construction can be viewed as an interactional achievement rather than the mere reporting of mental events. A multidisciplinary perspective which combines qualitative analysis with other forms of analytic technique may explain subtle differences between participants with hippocampal lesions and control participants.     

Selection history-driven signal suppression

ABSTRACT

The control of attention is influenced by current goals, physical salience, and selection history. Under certain conditions, physically salient stimuli can be strategically suppressed below baseline levels, facilitating visual search for a target. It is unclear whether such signal suppression is a broad mechanism of selective information processing that extends to other sources of attentional priority evoked by task-irrelevant stimuli, or whether it is particular to physically salient perceptual signals. Using eye movements, in the present study we highlight a case where a former-target-colour distractor facilitates search for a target on a large percentage of trials. Our findings provide evidence that the principle of signal suppression extends to other sources of attentional priority beyond physical salience, and that selection history can be leveraged to strategically guide attention away from a stimulus.     

The contribution of the human medial temporal lobe to perception: bridging the gap between animal and human studies.

The medial temporal lobe (MTL) has been considered traditionally to subserve declarative memory processes only. Recent studies in nonhuman primates suggest, however, that the MTL may also be critical to higher order perceptual processes, with the hippocampus and perirhinal cortex being involved in scene and object perception, respectively. The current article reviews the human neuropsychological literature to determine whether there is any evidence to suggest that these same views may apply to the human MTL. Although the majority of existing studies report intact perception following MTL damage in human amnesics, there have been recent studies that suggest that when scene and object perception are assessed systematically, significant impairments in perception become apparent. These findings have important implications for current mnemonic theories of human MTL function and our understanding of human amnesia as a result of MTL lesions.
