Unimpaired short-term memory and rhyme judgement in congenitally speechless individuals: Implications for the notion of “articulatory coding”

In normal adults, concurrent articulation impairs short-term memory, abolishing both the phonological similarity effect and the word length effect when visual presentation is used. It also interferes with ability to judge whether visually presented words rhyme. It is generally assumed that concurrent articulation impairs performance because it prevents people from recoding material into an articulatory form. If this is the explanation, then individuals who are congenitally speechless (anarthric) or speech-impaired (dysarthric) should show the same impairments as normal individuals who are concurrently articulating—i.e. they should have reduced memory spans, fail to show word length and phonological similarity effects in short-term memory, and find rhyme judgement difficult. These predictions were tested in a study of 48 cerebral palsied individuals: 12 anarthric, 12 dysarthric, and 24 controls individually matched to the speech-impaired subjects. There was no impairment of memory span in speech-impaired subjects, who showed normal phonological similarity and word-length effects in short-term memory. Speech-impaired subjects did not differ from their controls in ability to tell whether names of pairs of pictures rhymed. These results challenge the notion that “articulatory coding” is implicated in short-term memory and rhyme judgement and suggests that processes such as rehearsal and phonemic segmentation involve generation of a more abstract central phonological code.     

Perceiving the language of films.

Children appear to be familiar with the language of film makers or at least to perceive and remember films less well when the rules of this cinematic language are broken. In this experiment a simple action sequence filmed from a static viewpoint was made up into two films of four shots. One film was edited according to the rules of directional continuity specified by Hollywood cinema, that is the four shots were presented so as to preserve the subject's direction of movement across cuts. The other film was edited disregarding these rules. Apart from this difference both films were identical. Children aged seven, nine, and thirteen years watched either of these films and reconstructed the action using pictures representing the four shots. The children who saw the conventional version were better able to reconstruct what they had seen than those who saw the unconventional version.     

Sugaring the Pill: Assessing Rhetorical Strategies Designed to Minimize Defensive Reactions to Group Criticism

People are considerably more defensive in the face of group criticism when the criticism comes from an out‐group rather than an in‐group member (the intergroup sensitivity effect). We tested three strategies that out‐group critics can use to reduce this heightened defensiveness. In all studies, Australians received criticism of their country either from another Australian or from a foreigner. In Experiment 1, critics who attached praise to the criticism were liked more and agreed with more than were those who did not. In Experiment 2, out‐group critics were liked more and aroused less negativity when they acknowledged that the problems they identified in the target group were shared also by their own in‐group. In both experiments, the ameliorative effects of praise and acknowledgment were fully mediated by attributions of constructiveness. Experiment 3 tested the strategy of spotlighting; that is, of putting on the record that you intend your comments to apply to just a portion of the group rather than to the whole group. This strategy—which did not directly address the attributional issues that are presumed to underpin the intergroup sensitivity effect—proved ineffective. Practical and theoretical implications for intergroup communication are discussed.
