Lab meeting schedule

Instructions

Lab meetings are on fridays starting promptly at 10:45am in 560 Evans. 20 minutes organizational business followed by a scientific presentation.

Current Czar: Shariq

You're welcome to switch dates individually, but talk to the one you're switching with, and let me (Shariq) know so that I can make the change in the schedule.

Individual sounds streams are modeled as successive and overlapping, amplitude and frequency modulated sound "textures".

• Title: A theoretical model of specific language impairment
• Abstract: Some form of developmental speech or language disorders affecting as many as 5-10% of all children (Leonard, 1998). While many disorders have been associated with specific problems in cognitive or linguistic development, specific language impairment (SLI) describes children with significantly delayed acquisition of language without evidence of brain damage, impaired hearing or vision, schizophrenia, autism or other neurological disorders (Tallal, 2004). As such, children with SLI show extreme difficulty in early language acquisition while other cognitive abilities appear to fall within the population norm. In many earlier theories of SLI, high-level, language-specific deficits were often hypothesized as the underlying cause of the delayed learning; however, findings over the last decade suggest that a more generic auditory deficit underlies the degraded phonological processing associated with SLI children (Leonard, 1998; Tallal et al., 1993, 1996, 1998; Wright et al.., 2000). Much of this literature indicates that impaired perception and discrimination of rapidly changing components of both speech and nonspeech stimuli undermines development of normal language abilities (Godfrey et al., 1981; Kraus et al.., 1996; McAnally & Stein, 1997; Nagarajan et al., 1999; Reed, 1989; Snowling et al.., 1986; Stark & Heinz, 1996a, 1996b; Werker & Tees, 1987; Wright et al., 2000; Goswami et al., 2002, Gaad et al., 2006), although some findings have questioned these findings (Heath & Hogben, 2004; White, Milne, et al., 2006; White, Frith, et al., 2006). Even within this body of research, there exist differing theories about the nature of the underlying deficit. Some groups have agued that deficits in rapid auditory processing (RAP) leads to impairment in the ability to perceive sounds characterized by brief or rapidly changing temporal cues, fundamental to speech perception (Fitch, et al., 1997; Benasich et al., 2002; Tallal et al., 2004), while an alternate hypothesis proposes that SLI develops due to a deficit in the perception of rhythmic timing (Goswami, 2002), which might subserve speech segmentation during language development. Neuroanatomical research suggests that deficits associated with SLI may well emerge in relatively low-level, subcortical auditory processing (Benasich et al., 2002). Here we propose a simple model of low-level auditory processing capable of explaining some of the specific deficits identified in SLI populations associated with both RAP and rhythmic perception. In this “spike coding” model (Smith & Lewicki, 2005 & 2006) sounds are decomposed into a highly sparse set of “spikes” representing the occurrence of acoustic events selected from a dictionary of learned acoustic features (kernel functions). Importantly, by optimizing these acoustic features to efficiently encode natural sounds the resulting code partitions time-frequency space in an identical fashion to the mammalian cochlear code (Smith & Lewicki, 2006). This model predicts that the peripheral auditory code should contain a diverse set of coding units, with some devoted to accurately tracking acoustic transients while others are devoted to tight frequency resolution. The research proposed here uses a combination of behavioral experiments and computation modeling to test whether deficits in RAP and rhythmic perception both emerge in this model from a disruption of the units responsible for tracking acoustic transients.

I don't have any exciting new results yet, but I want to be prepared to explain the method for when the excitement does start.

Depending on how long the above stretches out to, I'll also give an introduction to CUDA - nVidia's general purpose GPU API to start planting seeds inside your heads for the types of applications that could be sped up using graphics cards.

Is there a relationship between noticing a coincidence in a higher-level cognition sense, such as detecting "non-random" patterns in a series of coin flips, and experience-dependent changes in "attentional" preferences, such as developmental changes in looking times? Perhpas not but I'll spin a yarn in any case. I'll start with a review of Griffiths & Tenebaum (in press), "From mere coincidence to meaningful discoveries" (link here: http://cocosci.berkeley.edu/tom/papers/coincidences.pdf). Then I follow with some ill formed ideas of my own.
